Engineering functional kidney tissue using human iPS cells
… enabled the derivation of renal organoids from hiPSCs; these organoids might be a powerful tool with important implications for regenerative medicine, but meticulous assessment of the functional abilities of the induced nephrons is key to the use of these organoids in any application. Here, I …

Analyses of hematopoiesis and lineage commitment from ES and iPS cells
… Analyse der Kapazitäten verschiedener ES- und iPS-Zelllinien, die sich durch die Anzahl der gebildeten erythroiden, lymphoiden und myeloiden Zellen bestimmen ließen. Es war erwartet worden, dass iPS-Zellen, die aus hämatopoietischen Knochenmarkzellen durch ektopische Expression von Sox-2, Oct-4 …

THE CELL CYCLE GENES REGULATION OF IPS CELLS AND THE ROLE OF SWI/SNF CHROMATIN REMODELING ENZYMES DURING THEM DIFFERENTIATION
Lo stato di cellula pluripotente può essere raggiunto con l'espressione ectopica di alcuni fattori di trascrizione che possono riprogrammare le cellule somatiche. (Takahashi, K., e Yamanaka, S., 2006; Takahashi, K., e Yamanaka, S., 2007).

Using human induced pluripotent stem cells to model cystinosis
… accumulation of cystine within lysosomes in most cells of the body, however the kidney is the main organ affected. For poorly understood reasons, renal proximal tubule (PT) cells lose their functionality and degenerate in cystinosis, forming a characteristic “swanneck” lesion that leads to kidney …

Hematopoiesis: Functional Insights by Cell Fate Conversion
… is maintained by rare hematopoietic stem cells (HSCs) residing in the bone marrow (BM). HSCs may self-renew (the process whereby HSCs replicate to produce new HSCs) to preserve their own numbers, as well as initiate a highly coordinated hierarchical differentiation process that results in …

Defining and Controlling the Subtype Identity of Human Stem Cell-Derived Motor Neurons
… cell types affected in vivo. Embryonic stem (ES) cells have the pluripotency to generate all somatic cells types, and the invention of somatic cell reprogramming techniques has allowed the creation of cell lines with both ES-cell grade pluripotency--induced pluripotent stem (iPS) cells--and the …

O-linked N-acetylglucosamine in differentiation and gene expression of mouse and human pluripotent stem cells
… of mouse and human embryonic stem (ES) cells. Here we show that increased levels of O-GlcNAcylation in response to specific inhibition of O-GlcNAc hydrolase (Oga) hinder mouse ES cell differentiation. In addition to these findings, I could also demonstrate that increased O-GlcNAcylation …

Efficient In Vitro Development of Photoreceptors from Human Pluripotent Stem Cells
… retina relies on the insertion of new, healthy cells. Embryonic stem (ES) cells and induced pluripotent stem (iPS) cells are two possible sources of photoreceptors to restore vision. Previous data shows that human ES cells and iPS cells can be differentiated into photoreceptors and transplanted …

Human Stem Cells for Modeling Amyotrophic Lateral Sclerosis Disease Mechanisms and Modifiers
… now possible to derive induced pluripotent stem cells (iPS cells) from the somatic tissues of ALS patients and then to differentiate these iPS cells into motor neurons with the precise genetic makeup of the donor patient (iPS-MNs). Before iPS-MNs can be put to productive use, however, the iPS …

Novel Regulators of Somatic Cell Reprogramming
Somatic cells can be reprogrammed to induced pluripotent stem (iPS) cells by expression of defined embryonic factors. My thesis is focused on exploring the mechanisms underlying reprogramming using a secondary mouse embryonic fibroblast model that forms iPS cells with high efficiency upon inducible …

Induced pluripotency and reprogramming by defined factors
… of nuclear equivalency between adult somatic cells. However the molecular mechanisms of somatic cell reprogramming have remained largely a mystery. Recent advancements in epigenetic reprogramming by defined factors provide new opportunities to explore factors that regulate induction of …

Conversion of equine umbilical cord matrix mesenchymal stem cells to the trophectoderm lineage using the Yamanaka reprogramming factors
Induced pluripotent stem (iPS) cells that possess embryonic stem (ES) cell-like properties are generated through the use of the Yamanaka transcription factors, OCT4, SOX2, KLF4, and MYC (OSKM). Advanced transgene delivery methods utilizing non-integrating viruses for transduction of target cells …

Induced-Pluripotent Stem-Derived Neuronal Progenitor Cells As A Novel Treatment For Neurodegenerative Diseases
… therapies, as neuronal progenitor (NP) cells grafting, are promising therapies for patients affected with neurodegenerative diseases like Creutzfeldt-Jakob Disease (CJD). At this time there is no effective treatment or cure for CJD. The disease is inevitably fatal and affected people …

Modularity in Somatic Cell Reprogramming
… to achieve distinct cell fates, including stem cells. Deriving induced pluripotent stem (iPS) cells has thus emerged as a critical approach in personalized regenerative medicine that provides an exclusive platform to study human development ex utero, engineer complex tissues, and build new …

Integration and function of new neurons generated from fibroblasts and adult neural stem cells in the pathological brain
… neurons – new neurons born from neural stem cells in the adult brain, and new neurons in the sense that they were generated from fibroblasts. Papers One and Two focused on the new neurons generated from neural stem cells in the SVZ and SGZ after pathological insults. We investigated how the …

Investigation of pancreatic beta cell differentiation and function, and global profiling analysis of diabetes serum for the identification of disease biomarkers
… compared to glucose responsive MIN6 cells. Functional investigations involving knockdown of mir-200a, mir-130a and mir-410 in MIN6 cells exhibiting GSIS resulted in reduced GSIS. This suggested that these three miRNAs functioned in supporting the capability of MIN6 cells to secrete …
