▼ Ischemic heart disease is the leading cause of death
globally, which takes more than 17.7 million lives every year (WHO,
2018), yet current treatments and procedures cannot restore cardiac
tissue lost due to ischemia. One of the goals for regenerative
medicine is to use human
induced pluripotent stem cell derived
cardiomyocytes (hiPSC-CMs) as a renewable cell source to replace
lost cardiomyocytes. The most significant limitation to the use of
hiPSC-CMs in regenerative medicine is our lack of understanding of
their biology, including their maturity state. To address this, a
series of experiments were carried out using photolithography and
microcontact printing techniques to create single cell patterns for
hiPSC-derived cardiomyocytes to examine their structure and
development. The specific patterns used in the experiments were
rectangles with an aspect ratio of 1:5 that were 1500 μm2. The
hiPSC-CMs were harvested and plated on either stiff silanized glass
or soft polyacrylamide (PAA) gels and analyzed with
immunocytochemistry. Using specific shape constraints, cytoskeletal
and myofibril structural organization were quantified to
characterize the structural maturity of the hiPSC-CMs. Results
demonstrate that with the addition of phenylephrine (PE), hiPSC-CMs
attach to the patterned surface, fill the shape, and provide larger
and more aligned sarcomeres. The specific patterns on a soft
substrate elicit greater structural maturity, which can be seen
three days after microcontact printing.

▼ Hematopoietic
stem cell (HSCs) therapy in the form of bone marrow transplantations has been used
successfully in the clinic for over 40 years and continues to save lives daily. Clinical
stem cell
transplantations are required to reconstitute the hematopoietic system of cancer patients that have
undergone chemotherapy and/or irradiation. Nevertheless, there are still many obstacles with the
clinical use of HSCs, including limited availability of transplantable HSCs, donor matching and graft
versus host reaction and the difficulty to expand HSCs in vitro. Embryonic
stem cells (ESCs) and/or
induced pluripotent stem cells (iPSCs) could offer a solution to this problem by providing a means to
generate HSCs in vitro. The knowledge to achieve this will likely come from our understanding of the
origin of HSCs in the embryo. In this review, I will discuss the ontogeny of HSCs and the prospects of
using ESCs and/or iPSCs to generate HSCs.

▼ Bovine adipose-derived stem cells (ADS), a form of adult stem cells, are somatic cells that have similar characteristics of embryonic stem (ES) cells. Bovine ADS cells possess multipotent capabilities and have been found to express pluripotency genes associated with ES cells. The unique properties of ADS cells make them a desirable source for reprogramming experiments. The goal of reprogramming experiments is to transform somatic cells from a differentiated state to a pluripotent state. When somatic cells reprogram, there are certain epigenetic changes or modifications that must occur in order to successfully reprogram the nucleus. Epigenetic modifications will change the chromatin configuration without changing the DNA sequence. Somatic cells can be exposed to small molecules that may be able to reduce the chances of having incomplete chromatin modification. Two epigenetic modifying factors are a DNA methyltranferase inhibitor, zebularine (Zeb), and a histone deacetylase inhibitor, valproic acid (VPA). By inducing gene expression with the epigenetic modifiers, the cells may be stimulated to reprogram more efficiently than cells with lower gene expression. In the first experiment, three bovine ADS cell lines were treated with VPA or Zeb to observe the changes in expression levels of Oct4, Sox2, and Nanog (pluripotency-associated genes). The cells were treated for a period of 5, 7,10, or 14 days. VPA led to the highest increase of the pluripotency genes; however, both treatments may have produced a partial reprogramming. This partial reprogramming may result in the bovine ADS cells reaching complete pluripotency when combined with a reprogramming technique. In the second experiment, three bovine ADS cell lines were treated with VPA or Zeb for five days then followed with transduction using lentivirus. Oct4, Sox2, and Nanog were increased the highest when using epigenetic modifiers. Statistical differences for expression of the pluripotency-associated genes were found for cells treated with zebularine. While it was thought that viral transduction in combination with epigenetic modifiers would produce higher expression levels of the pluripotency-associated genes, this was not found to be true in this experiment.

▼ One of the characterizations of Parkinson’s disease (PD) is the motor symptoms caused by the loss of the dopaminergic neurons of the substantia nigra pars compacta. The disease affects about 1% of the world population above 60 years old and is second most common neurodegenerative disorder, after Alzheimers disease. The mechanisms underlying the pathology of PD are not well understood and there is no available cure up tot this date. The rather selective loss of the dopaminergic neurons of the substantia nigra pars compacta makes the disease suitable for cell-replacement therapies. Currently
pluripotent stem cells represent the most promising source for the derivation of dopaminergic neurons. Human embryonic
stem cells are the best studied type of
pluripotent stem cells and have been successfully transplanted into animal models for PD, however another type of
pluripotent stem cells, namely
induced pluripotent stem cells, hold a greater potential for personalized patient-specific
stem cells therapy and disease-specific disease modeling.

▼ Future use of
pluripotent cells for regenerative
medicine will require the derivation and characterization of new
cell lines in clinical grade conditions. Removing potential sources
of contamination, such as cell culture components sourced from
animals, will aid the regulatory approval for future
stem cell
based therapeutics. In this dissertation, I describe the
development of a xenobiotic-free cell culture system for the
derivation and maintenance of human
pluripotent cell lines. I have
derived >40 hiPSC lines and one hESC line in the xeno-free cell
culture conditions with maintenance of pluripotency charcacterized
by morphology and immunocytochemistry marker expression for >50
passages and >30 passages respectively. The hESC line, USC-01
and several hiPSC lines derived for this study demonstrate highly
similar gene expression patterns although slight differences are
apparent. USC-01 and several hiPSC lines demonstrate the ability to
differentiate into
cells displaying characteristics of all three
germ layers in an embryoid body differentiation assay. Further
examination of the process of reprogramming somatic
cells to a
pluripotent state at both the RNA and protein expression levels
indicates several genes/markers selective for hiPSCs achieving a
pluripotent state most similar to the “gold-standard” of
pluripotency possessed by hESCs. This study confirms the usefulness
of the markers TRA-1-60, E-Cadherin and EpCAM for live-cell
selection of the best hiPSC colonies and also demonstrates the
usefulness of the marker GCTM-2. Expression analysis of colonies
undergoing reprogramming also indicates that the genes FOXD3, CDH3,
LCK, EDNRB, EPHA1, SOX2, and HAS3 are active in only a small subset
of colonies 30 days after transfection of the piggyBac transposon
reprogramming cassette. Since these genes are active in all hESC
and most hiPSC positive control lines tested, confirmation of their
activation could be used to select reprogramming hiPSC colonies
most likely to achieve a
pluripotent state similar to hESCs.
Increased selection and derivation efficiencies of hiPSC lines
demonstrating high fidelity to the hESC
pluripotent state will
streamline the generation of hiPSC lines for future testing as a
replacement for hESCs in regenerative medicine.

▼ Fragile X-associated tremor/ataxia syndrome (FXTAS) is an adult onset neurodegenerative disorder affecting carriers of premutation expansions (55-200 CGG repeats) of the fragile X mental retardation 1 (FMR1) gene. The clinical features of FXTAS, as well as various forms of clinical involvement in carriers without FXTAS, are thought to arise through a direct toxic gain-of-function of the FMR1 mRNA containing the expanded CGG repeat.
A singular difficulty in the study of cellular regulation in FXTAS, as with most other neurogenetic disorders, is background genetic variation between/among cases and controls. To circumvent this problem, a novel approach was taken whereby single allele sub-clones were derived from a single individual who was profoundly mosaic for CGG repeat size, with CGG repeats in individual alleles ranging from the normal range (<50 CGG repeats) to well into the full mutation range (>700 CGG repeats). Sub-clones with expanded CGG repeat alleles, and those with CGG repeats in the normal range, thus represent background isogenic case-control comparison groups, since all clones derive from a single individual.
In order to generate clonal fibroblast cell lines from the CGG repeat size mosaic, it was necessary to first develop a protocol that would successfully isolate single
cells and allow for their efficient expansion. Once the protocol was established, a PCR-based method was used to genotype with respect to CGG repeat size each of the clonal cell lines. Through this process, fifteen clonal lines have been established to date, with representatives from normal (<55 CGG repeats), premutation (55-200 repeats) and full mutation (>200 repeats) ranges. These clonal lines are currently being characterized with respect to FMR1 gene expression (FMR1 mRNA and protein levels). The current clonal library forms the basis for our effort to reprogram the fibroblast cell lines into
induced Pluripotent Stem Cells (iPSCs) with the intention of further differentiating the
cells into neural progenitor
cells, and subsequently, functional neurons.
This research project was conducted in the department of Biochemistry and Molecular Medicine, University of California, Davis, School of Medicine, in the laboratory of Dr. Paul J Hagerman.

▼ For many years, scientists have been trying to elucidate the molecular mechanisms that convey pluripotency and self-renewal to stem cells. With this valuable knowledge, they hoped to discover relevant information in the development, growth and regeneration of cells, tissues, and organisms that allow organisms to live as long as they do. These characteristics were once thought to be present only in embryonic stem cells (ESCs), and a few adult multipotent cells such as hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). Recent studies have tapped into the potential of our once thought to be terminally differentiated adult cells to produce self-renewable, pluripotentiating cells, now termed induced pluripotent stem cells (iPSCs). This critical review will discuss the advantages and limitations of the methods developed to generate and characterize iPSCs. Advantages and challenges of the use of iPSCs in applications such as research and therapeutics will also be discussed.

▼ Human pluripotent stem cells (hPSCs) are powerful tools to aid in the interrogation of the mechanisms of pathology of developmental disorders as well as modeling the development of embryonic and adult tissues. In this work, we attempted a
patient-specific disease in a dish model of the craniofacial disorder Treacher Collins Syndrome (TCS) and the directed differentiation of brown adipocytes from hPSCs. The TCS model was unable to replicate the expected phenotype of reduced neural crest
cell numbers or migratory potential. This shortcoming has been putatively attributed to reducing and high antioxidant conditions of the culture medium. Modulating brown adipocyte activity in humans has become an attractive therapeutic target for obesity
and related metabolic disorders such as type 2 diabetes. Murine models suggest the brown adipose organ is capable of significant changes in body mass and circulating levels of insulin and glucose. Methods to interrogate human brown adipocyte
functionality have been based on adult primary cells or overexpression systems. Here we report a robust and efficient chemically-defined method to differentiate human pluripotent stem cells into brown adipocytes through a developmentally appropriate
paraxial mesoderm intermediate. These adipocytes display characteristics of mature brown adipocytes including marker expression, responsiveness to stimulation, enhanced metabolic activity, thermogenic capacity, lipolysis, and utilization of fatty acids.
These cells are capable of being maintained in culture for several weeks, are amenable to passage, and upon transplantation in mice can give rise to adipose depots that maintain both morphological and functional properties. We propose that these cells
are appropriate for modeling brown adipocyte development in vivo, elucidating basic biological cell fate decisions and branch points and as a platform for high-throughput drug screening to identify putative therapeutic targets to combat obesity and
related disorders.

▼ Human pluripotent stem cells (hPSCs) are powerful tools to aid in the interrogation of the mechanisms of pathology of developmental disorders as well as modeling the development of embryonic and adult tissues. In this work, we attempted a
patient-specific disease in a dish model of the craniofacial disorder Treacher Collins Syndrome (TCS) and the directed differentiation of brown adipocytes from hPSCs. The TCS model was unable to replicate the expected phenotype of reduced neural crest
cell numbers or migratory potential. This shortcoming has been putatively attributed to reducing and high antioxidant conditions of the culture medium. Modulating brown adipocyte activity in humans has become an attractive therapeutic target for obesity
and related metabolic disorders such as type 2 diabetes. Murine models suggest the brown adipose organ is capable of significant changes in body mass and circulating levels of insulin and glucose. Methods to interrogate human brown adipocyte
functionality have been based on adult primary cells or overexpression systems. Here we report a robust and efficient chemically-defined method to differentiate human pluripotent stem cells into brown adipocytes through a developmentally appropriate
paraxial mesoderm intermediate. These adipocytes display characteristics of mature brown adipocytes including marker expression, responsiveness to stimulation, enhanced metabolic activity, thermogenic capacity, lipolysis, and utilization of fatty acids.
These cells are capable of being maintained in culture for several weeks, are amenable to passage, and upon transplantation in mice can give rise to adipose depots that maintain both morphological and functional properties. We propose that these cells
are appropriate for modeling brown adipocyte development in vivo, elucidating basic biological cell fate decisions and branch points and as a platform for high-throughput drug screening to identify putative therapeutic targets to combat obesity and
related disorders.

▼ Recently,
pluripotent cells that are not derived from an embryo have been generated. These so called
induced pluripotent stem cells (iPS
cells) are
pluripotent stem cells that are
induced from mouse or human somatic
cells by introduction of different factors. These iPS
cells are similar to ESC in pluripotency, morphology, proliferation, teratoma formation, gene expression and DNA methylation patterns.
Here a comprehensive overview and comparison of the currently available technologies for iPS
cells reprogramming have been presented. iPS cell reprogramming has promising new biomedical applications, such as the generation of patient specific iPS
cells for disease modeling and drug discovery and eventually the generation of customized iPS
cells for therapeutic application, such as cell therapy.

▼ Abstract. Although neural and mesenchymal stem cells have been well-known to have a strong glioma tropism, this activity in induced pluripotent stem cells (iPSCs) has not yet been fully studied. In the present study, we tested tumor tropic activity of mouse iPSCs and neural stem cells derivedfrom the iPSC (iPS-NSCs) using in vitro Matrigel invasion chamber assay and in vivo mouse intracranial tumor model. Both iPSC and iPS-NSC had a similar potent in vitro tropism for glioma conditioned media. The migrated iPSCs to the gliomas kept expressing Nanog-GFP gene, suggesting no neuronal or glial differentiation. iPSCs or iPS-NSCs labeled with 5-bromo-2-deoxyuridine were intracranially implanted in the contralateral hemisphere to the GL261 glioma cell implantation in the allogeneic C57BL/6 mouse. Active migration of both stem cells was observed 7 days after implantation. Again, the iPSCs located in the tumor areaexpressed Nanog-GFP gene, suggesting that the migrated cells were still iPSCs. These findings demonstrated thatboth iPSCs and iPS-NSCs had potent glioma tropism and could be candidates as vehicles in stem cell-based glioma therapy.

▼ Advancement of
stem cell therapy is dependent upon the practicality, safety, and efficacy of the
cells being evaluated for clinical application. Over the past decade, the need for banked
stem cells which are readily available for use at the time of a patient's diagnosis has become apparent. The overall goal of this dissertation research was to compare
induced pluripotent stem cells (iPSCs) to bone marrow-derived mesenchymal
stem cells (MSCs), first in terms of their ability to be generated from genetically diverse individuals, and then in terms of their immunogenic and immunomodulatory properties for potential allogeneic use. It has previously been demonstrated in mice that genetic background affects the proliferation and differentiation rates of MSCs. The purpose of our first study was to determine if genetic background affects the efficiency of generating iPSCs from mice. Results of this study confirmed that genetic background does affect both the efficiency of generating iPSCs during the early stages of reprogramming as well as the
pluripotent stability of the iPSCs during later stages of reprogramming. The results also confirmed the need to understand the immunogenic and immunomodulatory properties of these
cells for potential allogeneic application given that it may not be feasible to generate iPSCs from all individuals or to wait for the time that it takes to generate iPSCs and then screen them for safety and efficacy. The purpose of our second study, therefore, was to evaluate the in vitro immunogenic and immunomodulatory properties of murine iPSCs compared to MSCs using modified mixed leukocyte reactions. Our comparisons revealed that iPSCs generated through both lentiviral and piggyBac reprogramming methods had similar immunogenic properties as MSCs, and more potent immunomodulatory effects than MSCs. This information is critical when considering the use of iPSCs in the place of MSCs for both regenerative medicine and transplant medicine. Further studies must be performed, however, in order to determine if iPSCs retain their immunogenic and immunomodulatory properties upon differentiation into specific cell or tissue types. With this knowledge, we then shifted the focus of our third study to the horse, which is a valuable model for the human immune response. The purposes of this study were to immunophenotype MSCs from horses of known MHC haplotype and to compare the immunogenicity of MSCs with differing immunophenotypes, particularly in regards to MHC class II expression, through modified mixed leukocyte reactions. Results of this study demonstrated for the first time the extreme heterogeneity that exists in MHC class II expression by equine MSCs and that MHC class II positive equine MSCs are capable of inciting an immune response in vitro. This knowledge is critical for the treatment of our equine patients as well as for studies using the horse as an animal model for human diseases. Future experiments to determine if we can modulate this MHC class II expression in culture will be of great interest prior to…

▼ The derivation of pluripotent stem cells (now termed induced pluripotent stem cells, iPSC) from mature somatic cells was a finding of seminal importance to fundamental cell biology. Thus established iPSC technology has been predicted to advance fields that previously relied on the ethically disputed use of embryonic stem cells. Being pluripotent (able to differentiate into every cell type present in the human body) and sharing most other characteristics with embryonic stem cells, but being much readier obtainable and their derivation free from ethical restraints, human induced pluripotent stem cells (hiPSC) provide access to cell types and insights into cell processes previously unattainable to researches. For this thesis, a hiPSC line was established from a skin biopsy donated by a Down’s syndrome patient. Most of what is known today about the molecular neurobiology behind this disease has been gathered from mice models or human post mortem studies, but this has a limited extrapolation potential to early human brain development in DS patients, as Down’s syndrome is an inherently human disease whose defining phenotype is established early during embryonic development. Having access to human pluripotent cells able to recapitulate the events of early neurogenesis is thus invaluable to the understanding of the mechanisms of this disorder. In parallel, work has been performed on optimizing iPSC reprogramming protocol. By exchanging one of the transcription factors used for reprogramming with a reporter gene, genomic integration of reprogramming factors has become possible to be traced visually, enabling more efficient selection of reprogrammed iPSC colonies.

▼ In mammals, overexposure to loud noise, ototoxic medication or even ageing can incur irreversible damage to the sensory hair cells and spiral ganglion neurons (SGNs) resulting in sensorineural hearing loss (SNHL). Currently, the cochlear implant is the only available treatment for SNHL, but its functionality is dependent on a healthy complement of SGNs. Therefore in cases of severe SNHL, where the numbers of SGNs are significantly depleted, the efficacy of this neural prosthesis may be compromised.
Using stem cells to replace damaged SGNs is an emerging therapeutic strategy for deafness. Whilst previous studies have explored the potential for several stem cell types, particularly human embryonic stem cells (hESCs) to replace SGNs, it will eventually be important that transplanted cells are from an autologous source. This thesis therefore aims to explore the potential of human induced pluripotent stem cells (hiPSCs) for SGN replacement. These cells offer the option of transplanting SGNs generated from a patient’s own cells to potentially restore hearing function and/or improve the efficiency of the cochlear implant.
To investigate the potential of hiPSCs, it is first necessary to assess their potential to differentiate into a SGN lineage. In the first study of the thesis, an established neural induction protocol was used to differentiate two hiPSC lines (iPS1 and iPS2) and one human embryonic stem cell line (hESC, H9) towards a neurosensory lineage in vitro. Immunocytochemistry and qRT-PCR were used to analyse the expression of key markers involved in SGN development, at defined time points of differentiation. The hiPSC- and hESC-derived neurosensory progenitors expressed the dorsal hindbrain and otic placodal markers (PAX7 and PAX2), pro-neurosensory marker (SOX2), ganglion neuronal markers (NEUROD1, BRN3A, ISLET1, ßIII-tubulin, Neurofilament kDa 160) and sensory SGN markers (GATA3 and VGLUT1) over the time course examined. The hiPSC-and hESC-derived neurosensory progenitors had the highest expression levels of the sensory neural markers at 35 days in vitro. Whilst all cell lines analysed produced neurosensory-like progenitors, variabilities in the levels of marker expression were observed between hiPSC lines and within samples of the same cell line, when compared to the hESC controls. Thereby, suggesting that hiPSCs have a more variable differentiation potential compared to the hESCs.
The functionality of the hiPSC-derived neurons was next assessed using patch clamp electrophysiology and in vitro co-culture assays. It was found that the cells were capable of firing action potentials in response to depolarisation and exhibited a phasic profile of activity, thus indicating that the neurons were physiologically active. Following co-culture of cochlear explants or denervated explants with hiPSC- and hESC-derived neurons, their neural processes were observed to make direct contact and form extensive synaptic connections with inner and outer hair cells in vitro. However the hiPSC-derived neurons were…

▼ Human embryonic stem cells (hESC) and induced pluripotent stem cells (hiPSC) are pluripotent stem cells (hPSCs) that have the capacity to differentiate into a panoply of various cell types and to serve as a model for human development. Nevertheless, it is unknown whether in vitro development of hPSCs mirrors in vivo human development. We performed comprehensive transcriptome profiling to compare hPSC-derived progeny with tissue-derived counterparts. While hESC and hiPSC make nearly identical progeny for the neural, hepatic and mesenchymal lineages, these hPSC-derived progeny maintained, regardless of the cell lineage, the expression of genes normally associated with early development, including LIN28A, LIN28B and DPPA4. These data and expression patterns in early human fetal tissue suggested the hPSC-derivatives were reflective of very early human development. The LIN28/let-7 pathway has been known to regulate development. We hypothesize that high Lin28 and low level let-7 activities may be inhibiting the developmental maturity in hPSC-derivatives. In addition, such a LIN28/let-7 expression pattern is also thought to contribute to tumor aggressiveness. We have established a human cell-based system to screen for small molecules that could modulate LIN28/let-7 activity. This screening could potentially unveil powerful small molecules that could modulate developmental maturity and therapeutically combat cancer. Previous reports and our own transcriptional profiling indicate that hPSCs are suitable for modeling early human development. Epithelial to mesenchymal transitions (EMTs) are thought to be essential to generate diversity of tissues during early fetal development, but these events are impossible to study at the molecular level in vivo in humans. The first EMT event in human development occurs just prior to generation of the primitive streak. Because hPSCs are thought to most closely resemble cells found in epiblast stage embryos prior to formation of the primitive streak, we sought to model this first human EMT in vitro with hPSCs. We have demonstrated the EMT progression in hPSCs with embryoid bodies. We also identified PTK7 as a marker of this EMT population, which was used to purify these cells for identification of novel markers of human germ layer development.

▼ The complexity of life exhibited in humans and other living creatures has drawn many to investigate the principles associated with organismal growth and development. A few broad questions: How do tissues develop into specified organs? How are these tissues maintained? Do they become different tissues? Scientific research has incessantly been seeking answers to these as well as a plethora of other questions. While on a quest to better understand developmental biology, investigators discovered unique populations of stem cells within a variety of tissues, which retain both varying degrees of developmental plasticity and their potential for self-regeneration. This thesis provides a brief review discussing the development and history of stem cells in medicine and associated research on these cells and their potential clinical applications.
Substantial attention has been paid to pluripotent embryonic stem cells (ESC) and induced pluripotent stem cells (iPSC) which are able to be recapitulate ESC properties through the in vitro reprogramming of somatic cells. While, the ethical and legal issues have greatly hindered the use of ESCs this has made the benefit of iPSCs so great. An interconnected network of pluripotency-associated genes, integrates external signals and exerts control to maintain the state of pluripotency. Recent research has proven the pluripotency regulatory network to be flexible such that the underlying principles promise unprecedented opportunities for scientific study and regenerative medicine. Additional topics reviewed here include vast clinical applications of stem cells as well as their notable limitations.

▼ Embryonic stem cells (ESCs) are pluripotent cells derived from the early embryo and are able to differentiate into cells belonging to the three germ layers. They are a valuable tool in research and for clinical use, but their applications are limited by ethical and technical issues. In 2006 a breakthrough report described the generation of induced pluripotent stem cells (iPSCs). IPSCs are ESC-like cells generated from somatic cells by forcing the ectopic expression of specific transcription factors. This circumvents the ethical issues about the use of embryos in research and provides multiple opportunities to understand the mechanisms behind pluripotency. The aim of this project was to generate sheep iPSCs and characterise them. In order to learn the technique I initially repeated the original iPSC methodology: the putative mouse iPSCs I have generated display a morphology typical of ESCs, characterised by a high nuclear to cytoplasmic ratio, and form colonies with neat edges and smooth domes. These cells are positive to Nanog, a marker of pluripotency, and can give rise to cells belonging to the mesodermal and the ectodermal lineages when differentiated in vitro. Since the main aim of the thesis was the derivation of sheep pluripotent cells, once established the protocol in mouse, I then moved to the generation of ovine iPSC colonies. The cells I have generated have a morphology similar to that of mouse ESCs, express markers of pluripotency such as alkaline phosphatase and Nanog and can differentiate in vitro and in vivo into cells belonging to the three germ layers. Additionally, these ovine iPSCs can contribute to live born chimeric lambs, although at low level.

▼ Diabetes is a chronic disease characterized by increased blood sugar because of dysfunctional
glucose homeostasis by the beta cells in the pancreas. Functional beta cells can be generated by
primary cells or stem cells. Primary cells are isolated directly from tissues (blood or bone marrow)
and retain the morphological and functional characteristics of their tissue of origin. However,
they have a finite period of cell culture, a limited potential for self-renewal and differentiation
and are more sensitive than stem cells, they often require additional nutrients and growth factors.
In contrast, stem cells allow to investigate basic biological processes, manipulate cellular
functions, establish new methods, or perform preliminary screenings. Considering the limitations
of the primary cells, stem cells can be an alternative source. Stem cells are at the forefront of
research in cell therapy, drug discovery, and disease-modelling. Generation of pancreatic beta
cells is possible by differentiating human induced pluripotent stem cells (hiPS cells), although in
stem cell research, efficiency of mature beta cells generation is a key problem (optimal efficiency
at 80%, current efficiency at 20%). This project first aims to improve efficiency of pancreatic beta
cell generation from hiPS cells by performing six differentiation processes following the same
protocol and later screening for beta cell production at different stages of the differentiation
process. It uses a wild type and two MafA-GFP reporter iPS cell lines, where MafA as a critical
beta-cell-specific transcription factor is tagged with GFP by using CRISPR/Cas9 technology.
Second, flow cytometry and immunofluorescence analysis are used at different stages of the
differentiation process to characterize the differentiated cells to confirm faithful expression of
MafA. Expression of GFP corresponds to expression of MafA in adult beta cells, since MafA is
only present in mature beta cells, which this confirms complete differentiation and maturation
of iPS cells into beta cells. The results obtained from the differentiation processes showed low
level of reproducibility, although this project was successful in showing the GFP and MafA
expression of MafA reporter lines. The MafA reporter lines successfully expressed GFP signals
(~11% efficiency) at stage 7 of beta cell differentiation.

▼ Immunotherapy traditionally made use of biological agents such as cytokines and monoclonal antibodies. Such first generation therapies lack antigen specificity and fail to induce immunological memory, suggesting that cell therapies may provide the next generation of treatments that are more discerning in their mode of action. Nevertheless, difficulties in obtaining sufficient immunologically-relevant cell types from patients has limited their success. Given that induced pluripotent stem cells (iPSC) may be generated from patients, we have investigated the feasibility of deriving two cell types whose availability is restricted in vivo: regulatory T cells (Tregs) and CD141+ cross-presenting dendritic cells (DCs). We describe the optimization of protocols for differentiation and purification of CD141+ DCs, focussing on their utility as a therapeutic vaccine for HIV-1. We investigate their phenotype, chemotactic capacity, phagocytic ability and propensity to harbour infectious virus. We also assess their immunostimulatory capacity and ability to cross-present exogenous antigen to MHC class I-restricted T cells. Our findings led us to speculate that iPSC-derived DCs (iPDCs) possess fetal phenotype, which is characterised by excessive secretion of IL-10 and failure to secrete IL-12, under all but the most stringent conditions. We hypothesised that constitutive secretion of IL-10 may be responsible for maintaining the fetal phenotype, a hypothesis we tested by developing an appropriate mouse model. iPSCs were derived from WT and IL-10-/- mice and were shown to differentiate into iPDCs which recapitulate the fetal phenotype observed among human cells. However, loss of the endogenous Il-10 gene failed to restore full immunogenicity and IL-12 secretion. Finally, we developed protocols for differentiation of FoxP3+ Tregs from iPSCs, a feat that has not previously been achieved. These findings pave the way for the differentiation of Tregs from iPSCs reprogrammed from antigen-specific pathogenic T cells, thereby creating a source of Tregs with matched specificity for therapeutic intervention.

▼ Undifferentiated human embryonic
stem cells (hESCs)
grow on the extracellular matrix (ECM) substrate fibronectin (FN)
in defined feeder-free conditions. The ECM is part of the hESCs
pluripotent niche and supports their maintenance, but the
contribution to survival remains to be elucidated. Understanding
the mechanism of survival is particularly crucial in hESCs, since
it affects their expansion in cell culture and ultimately
translation of research to the clinic. HESCs bind to FN mainly via
α5β1- integrin, known to be upstream of important survival cascades
in other cell types. However, it is not understood if and how
FN/integrin binding supports those molecular pathways in the
context of
pluripotent hESCs. The aim of this work was to elucidate
the survival cascade downstream of the FN/integrin interaction in
hESCs. Initially, when hESCs were cultured on a non-integrin
activating substrate they initiated an apoptotic response that also
occurred when β1-integrin was selectively blocked with antibody,
leading the
cells to detach from FN. Integrin activation is
generally transduced within
cells via a complex adhesome of
scaffold and kinase proteins, among which the focal adhesion kinase
(FAK) plays a key role. Indeed, blocking β1-integrin resulted in
dephosphorylation of endogenous FAK in hESCs. When FAK kinase
activity was directly inhibited (with small molecule inhibitors),
hESCs responded by detaching from FN and activating caspase-3,
leading to an increase in apoptosis. Furthermore, flow cytometry
analysis showed that the population of hESCs that underwent
apoptosis still retained the pluripotency-associated marker NANOG.
FAK is a convergent point between growth factor signaling and the
PI3K/Akt pathway, with a well-reported role in the maintenance of
hESCs. Consistently, FN activated both AKT and its target the
ubiquitin ligase MDM2 at the protein levels, while pAkt was reduced
after β1-integrin blocking and FAK inhibition. Cell imaging showed
that MDM2, which regulates p53 degradation in the nucleus,
displayed reduced nuclear localisation after FAK inhibition,
opening the possibility for a change in the p53 balance in hESCs.
In fact, p53 protein increases after FAK inhibition corresponding
also to caspase activation. Further investigation explored if
FAK-dependent pathways are also implicated in the maintenance of
hESC pluripotency. Inhibition of FAK led the
cells that survived
apoptosis to lose
stem cell morphology, decrease
pluripotency-associated markers and change nuclear shape. Moreover,
a small pool of FAK was found in the nucleus of hESCs cultured on
FN, but decreased after FAK inhibition. FAK was also co-
immunoprecipitated with NANOG protein in standard hESC culture
while NANOG decreased after sustained FAK inhibition. This data
suggests that nuclear roles of FAK could support, together with the
cytoplasmic activation of the PI3K cascade, both survival and
pluripotency pathways requiring further investigation. In
conclusion, the original contribution of this work is to identify
in FAK the downstream…

▼ Advancements in medical management for spinal cord injury (SCI) have resulted in greatly improved survival rates following this devastating event; although medical interventions to regenerate the injured spinal cord and restore function remain limited. Neural
stem cells (NSCs) from embryonic or fetal/adult tissues sources show considerable promise in regenerative strategies for traumatic SCI. However, there are limitations with their use related to availability, immunogenicity, immunological rejection and uncertainty of mechanism. To address these issues, our laboratory has investigated the use of NSCs derived from
induced pluripotent stem (iPS)
cells generated using a non-viral and mutation-free approach. NSCs were generated from
pluripotent cells using a free-floating neurospheres methodology previously used by our lab. To delineate the mechanism of action, specifically the role of exogenous myelination, NSCs derived from wildtype (wt) and non-myelinating Shiverer (shi) iPS cell lines were used in a mouse thoracic SCI model with sub-acute intraspinal transplantation. Behavioral, histological and electrophysiological outcomes were analyzed to assess the safety and efficacy of this treatment. Variable neural propensity in the iPS cell lines were identified and overcome by agonizing the NOTCH pathway, yielding a clinically relevant population of NSCs for transplantation. The wt- and shi-iPS-NSCs were validated and shown to be equivalent except in myelination capacity. Both iPS-NSC lines were transplanted following thoracic SCI, but only the wt-iPS-NSC treatment resulted in a functional benefit. Wt-iPS-NSC transplantation resulted in significantly improved hindlimb locomotor function, histological outcomes and action potential amplitudes compared to the non-myelinating and cell-free controls. This supports remyelination as the key process by which NSC treatment provides a benefit following thoracic SCI. This work addresses a significant knowledge gap in the field of regenerative medicine for SCI. It demonstrated that
pluripotent cells, specifically iPS
cells, can be used to generate clinical relevant NSCs for application in SCI. Even though NSCs have been shown to provide a diverse range of functions in the spinal cord, remyelination is the predominate mechanism of recovery following thoracic SCI. This work will have significant impact in shaping how iPS-NSCs will be potentially translated to a clinical setting.

▼ Induction of pluripotency is a process that reverses the phenotype of terminally differentiated
cells. Somatic
cells,
induced by specific transcription factors, are reprogrammed to a
pluripotent state. The resulting
cells, called
induced pluripotent stem cells, have activated pluripotency-related genes and silenced genes of the somatic programme. Many studies have been done in order to elucidate the molecular mechanisms of reprogramming. Experimental data will increase our understanding of the reprogramming process and help to improve reprogramming strategies. Reprogramming somatic
cells occurs in phases. Pre-
induced pluripotent stem cells (pre-iPSCs) have been identified as an intermediate stage and will allow the study of the molecular pathways of reprogramming. Pre-iPSCs and iPSCs hold potential for regenerative medicine as well as the modelling of diseases.

▼ Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disease in which low levels of survival of motor neuron (SMN) protein lead to the degeneration of alpha motor neurons (MNs) in the spinal cord. The pathological mechanism of SMA is highly controversial and until recently it was not possible to obtain human MNs to study the disease. The development of induced pluripotent stem cell (iPSC) technology has made it possible to bypass this obstacle and iPSC-based models of SMA type I have already been validated by two separate groups. Encouraged by these pioneering findings I have produced and characterized iPSCs from several members of a discordant consanguineous family in which four haploidentical siblings share the same homozygous SMNl mutation, but nonetheless show different phenotypes of the disease. I have differentiated iPSC clones from three of the siblings and the carrier unaffected mother, as well as a control unaffected clone and a clone derived from a patient with SMA type I, into ISL1+/ChAT+ MNs. No obvious phenotypic difference was observed between the MN cultures of the siblings during the period of study, but cells from the SMA type I patient did show an impaired ability to form rosettes. The study of SMN and PLS3 levels during the differentiation from iPSCs to ChAT+ MNs showed a gradual decay of these proteins during MN development in all clones. Furthermore, SMN protein levels did not correlate with the pattern of mRNA expression, c suggesting the existence of post-transcriptional and/or post-translational regulation of full-length SMN (FL-SMN) transcripts and protein. The FL/.d7-SMN mRNA ratio and total SMN (tSMN) mRNA levels were found to be possible biomarkers to distinguish unaffected individuals from SMA patients and the severity of SMA pathology, respectively. PLS3 protein level was higher in the SMA type IV/asymptomatic sibling than in two of the type III SMA siblings, but it could not be confirmed as a modifier factor in the family. These results suggest that SMN levels are regulated during MN development, and that low levels may impair the generation of rosettes but not necessarily of MNs. SMN levels in MNs only show minor differences between patients, suggesting that there may be a threshold after which reduced levels of SMN within a narrow range become suddenly and increasingly detrimental unless modifier factors can compensate for the cellular function(s) lost. 3

▼ Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) derived from large mammals reproduce few characteristics displayed by rodent or human counterparts. This is complicated by the inherent plasticity of mammalian ESC/iPSC cultures that resemble a variety of developmental stages including the naïve and primed pluripotent states. Defining the extrinsic signals that modulate the developmental identity of canine ESC/iPSC (i.e. primed versus naïve) will improve knowledge integration with more sophisticated rodent and primate research. In this thesis, I sought to determine if manipulation of the culture environment can promote nuclear and metabolic reprogramming of canine cell lines towards a more primitive state of pluripotency. Using growth factors and kinase inhibitors to modulate pluripotency of canine ESCs (cESCs), I demonstrated that cESCs exhibit the plasticity to adopt multiple developmental identities. I observed that lineage-specific differentiation of cESCs is influenced by pluripotent state modulation, coincident with changes to colony architecture, transcriptional and epigenetic markers of developmental maturity. I found that primed- and naïve-like cESCs exhibit pluripotent-state specific mitochondrial structure and function, including differential reliance on glucose oxidation pathways for steady-state proliferation in vitro. Lastly, using comparative sequence analysis and biochemical assays, I observed that evolutionary differences in genomic CpG density at pluripotency-associated promoters correlate with functionally relevant cytosine modifications to the induction and maintenance of pluripotency. I showed the utility of physiological metabolites that regulate 5-methylcytosine oxidation in promoting cellular and transcriptional features associated with early nuclear reprogramming of canine fibroblasts (e.g. mesenchymal-to-epithelial transition). Taken together, my work establishes a binary cESC model of primed- and naïve-pluripotent states, providing insight into shared and divergent features of pluripotency progression and acquisition in placental mammals.

▼ Current usage of human embryonic
stem cells (hES) and
induced pluripotent stem cells (iPS) in clinical therapies and personalized medicine are limited as a result of ethical, technical and medical problems that arise from isolation and generation of these
cells. Isolation of hES
cells faces ethical problems associated with their derivation from human pre-implantation embryos. The most controversial aspect of hES cell isolation targets the generation of autologous hES cell lines which requires the transfer of a somatic-cell nucleus from the patient to an enucleated oocyte. While already established embryonic
stem cell lines from IVF embryos can be used in a similar manner, lack of genetic identity can cause therapy rejection from the host, and prevent their use in personalized medicine.
Induced pluripotent stem cells on the other hand, are generated from somatic
cells that have been reprogrammed in vitro to behave like
stem cells. While these
cells can potentially be used for personalized medicine without the risk of rejection by the host system, derivation methods prevent their therapeutic use. The most efficient method used to generate iPS
cells involves usage of viral particles which can result in viral DNA being integrated in the host cell’s genome and render these
cells non-compliant for clinical therapies. Other methods not involving viral particles exist as well, but the reprogramming efficiency is too low and technical problems with generating large enough numbers of
cells prevent these methods from being feasible approaches for clinical therapies. Direct reprogramming of a differentiated cell into a developmentally more plastic cell would offer alternatives to applications in regenerative medicine that currently depend on either embryonic
stem cells (ES), adult
stem cells or iPS
cells. We hypothesize that Xenopus laevis egg cytoplasmic extract contains critical factors needed for reprogramming that may allow for non-viral, chemically defined derivation of human
induced pluripotent/multipotent
cells which can be maintained by addition of exogenous FGF2. In this thesis we investigated a new method for generation of multipotent
cells through determining the ability of select fractions of Xenopus laevis egg extract to induce multipotency in already differentiated
cells. We were able to identify select fractions from the extract that in combination with exogenously added FGF2 can reprogram and maintain the reprogrammed
cells in an undifferentiated state. The findings of this work also determined that Xenopus laevis egg extract mRNA is required for achieving full reprogramming. The body of work presented in this thesis showed the ability of FGF2 isoforms to bind and activate select FGF receptor tyrosine kinases, act as extracellular mitogenic factors to support growth of hES
cells in an undifferentiated state as well bind to nuclear DNA and affect expression of endogenous genes. Moreover, we showed that all FGF2 isoforms can induce expression of
stem cell specific proteins in human dermal fibroblasts as well as…

▼ Myc is a critical factor for embryonic stem cell maintenance. It also enhances the reprogramming of fibroblasts by effecting widespread changes in gene expression, effectively silencing the somatic cell gene expression program. Significant
effort has been placed into identifying myc targets in embryonic stem cells as a step to define mechanisms of myc action. However, despite this, how myc regulates self-renewal and pluripotency remains unknown. To fill this gap, target genes and
interacting proteins of c-myc in embryonic stem cells have been identified on a global scale. Key interacting proteins include epigenetic regulators Smarca4 and LSD1, which are important regulators of gene activation and repression in embryonic stem
cells. Target genes of particular interest include the miR-17-92 cluster, through which myc acts to establish the cell cycle structure that is crucial for the maintenance of self-renewal. A second is the primitive endoderm specification factor Gata6. Myc
binds to the promoter region of Gata6 in pluripotent cells and directly represses its transcription. In the absence of c- and N-myc, pluripotent cells differentiate to endoderm, concomitant with an increase in Gata6 transcription. The demonstration that
myc represses Gata6 is a step toward defining mechanisms of pluripotent stem cell maintenance by myc. This mechanism of repression of lineage specific differentiation by myc was delineated by generating induced pluripotent cells, and inactivating c-myc
and N-myc simultaneously. These experiments demonstrate that c- or N-myc is an absolute requirement for maintenance of the embryonic stem cell state, and one mechanism of sustaining self-renewal is repression of primitive endoderm
differentiation.

▼ Stem cell technology is an invaluable tool in
tissue engineering and regenerative medicine, with
induced
pluripotent stem cells (iPSCs) providing the means to design:
autologous cell therapies, drug screening platforms and disease/
developmental models. However, the expansion of hiPSCs in vitro
typically relies on either the presence of a layer of supportive
feeder
cells, or the use of ill-defined matrices. Moreover,
following differentiation, iPSC-derivatives often lack the same
phenotypic traits as their native counterparts. As such, the field
of tissue engineering moves toward recapitulating the cell niche in
vitro, through the design of biomaterials for 3D cell culture. With
this in mind, the designs of new biomaterials are emerging all the
time. Of particular focus are 'hydrogels'; a water-swollen network
of polymeric fibres which entangle and/ or aggregate to form a
self-supporting construct. These fibres can be made of natural and/
or synthetic polymers. Of great interest are peptide hydrogels.
Peptide sequences can be designed to self-assemble into an array of
larger macromolecular structures. One family of self-assembling
peptide hydrogels (SAPHs) are based on an alternating sequence of
hydrophilic/ hydrophobic amino acid residues which self-assemble to
form beta-sheet nanofibres. Many variations of these SAPHs
currently exist within the literature, e.g. EAK, RADA and KFE, and
have already shown great promise in supporting the culture of many
different cell lineages; a promising substrate for
stem cell
culture and tissue engineering applications. Importantly, when
considering any biomaterial for 3D cell culture, it is vital to
determine whether the abundance of material interferes with the
method of analysis, either through interactions with the substrate
of interest, or a component(s) of the technique. The work presented
here is the first to outline the development of protocols for the
following applications: 1) the extraction of RNA from
cells
encapsulated in SAPHs for downstream quantitative polymerase chain
reaction (qPCR); and 2) the solubilisation of SAPHs and cell
proteins for downstream western blot analysis. For RNA extraction,
RNA was isolated from four peptide formulations - which vary in net
charge - using either: 1) precipitation-based extraction, or 2)
solid-state RNA binding to a silica membrane. The latter was more
effective at removing contaminants but both methods resulted in a
low yield - demonstrating a clear interference from the presence of
SAP. However, enzymatic degradation of the hydrogel construct prior
to RNA isolation significantly increased the amount of RNA
recovered. On the other hand, for western blot analysis, the focus
was on achieving complete solubilisation of both the
self-assembling peptide (SAP) monomer and cell proteins following
disruption of the hydrogel construct and the lysis of encapsulated
cells. The use of urea - unlike a detergent-based buffer
(Radioimmunoprecipitation assay buffer, aka RIPA) - in combination
with multiple cycles of ultrasonication, was able to…
