Project description:Pluripotency, the capacity of embryo-derived stem cells to generate all tissues in the organism, can be induced in somatic cells by nuclear transfer into oocyte, fusion with embryonic stem cells, and for male germ cells by cell culture alone. Recently, murine fibroblasts have been reprogrammed directly to pluripotency by ectopic expression of four transcription factors (Oct4, Sox2, Klf4, and Myc) to yield induced Pluripotent Stem (iPS) cells. Using the same four factors, we have derived iPS cells from human embryonic stem cell-derived fibroblasts, primary human fetal cells, and diverse cells of neonatal and adult human origin. The human iPS cells manifest the colony morphology, gene expression patterns, and epigenetic characteristics of human Embryonic Stem (hES) cells, and form well-differentiated teratomas in immune-deficient mice. These data demonstrate that defined factors can reprogram human cells to pluripotency, and establish a method whereby patient-specific cells might be established in culture.

Project description:In this study, we explored x-inactivation in monkey embryos (ICM and TE separately) and pluripotent stem cells (IVF derived ES, SCNT-derived ES and monkey iPS) To elucidate x-inactivation in experimentally reprogrammed pluripotent cells, we derived pluripotent stem cells by both SCNT and iPS approaches from same parental skin fibroblasts. We also compared gene patterns of those cells to IVF-derived counterpart. The transcriptomes of rhesus monkey embryonic stem cell lines derived by both SCNT (CRES) and iPS (RiPS) from same monkey skin fibroblasts were compared each other. Both experimentally reprogrammed cells were also compared with IVF-derived counterpart (ORMES23). Finally, the adult somatic skin fibroblasts were analyzed. Three biological replicates of each cell line (A, B, C) were analyzed.

Project description:The Human Induced Pluripotent Stem Cells Initiative (HipSci) project brings together diverse constituents in genomics, proteomics, cell biology and clinical genetics to create a UK national induced pluripotent stem cell (iPS cell) resource and use it to carry out cellular genetic studies. In this sub-study we performed Expression analysis using the Illumina HumanHT -12 Expression BeadChip on fibroblasts and iPS cells generated from skin biopsies from healthy volunteers.

Project description:The Human Induced Pluripotent Stem Cells Initiative (HipSci) project brings together diverse constituents in genomics, proteomics, cell biology and clinical genetics to create a UK national induced pluripotent stem cell (iPS cell) resource and use it to carry out cellular genetic studies. In this sub-study we performed Expression analysis using the using RNAseq of fibroblasts, peripheral blood mononuclear cells (PBMCs) and induced pluripotent stem cells (iPS cells) generated from the skin biopsies or blood of healthy volunteers. This experiment includes the data and expands the metadata from two obsolete ArrayExpress accessions (E-ERAD-216 and E-ERAD-327) for use in the Expression Atlas. For samples derived from E-ERAD-216 the raw data is stored in the European Genome-Phenome Archive (EGA) and is subject to access control. Data from E-ERAD-327 is stored in the European Nucleotide Archive (ENA) and is publicly available.

Project description:Herpes simplex virus type 1 (HSV-1) is a 152 Kb double stranded DNA alpha-herpesvirus, which establishes long life latent infection in sensory neurons. Most of our knowledge regarding HSV-1 latency comes from in vivo studies using small animal models, mainly rodents and rabbits, which are not naturally infected by HSV-1. Furthermore, these animal models do not fully recapitulate the species specific effects of human HSV-1 infection. Human cellular models utilize trigeminal ganglia removed from cadavers or, alternatively, neuron-like cells derived from cancerous cell lines that do not fully reflect effects on normal human neurons. This limitation poses the need to develop an in vitro model to investigate molecular details of the mechanisms underlying latency and reactivation in human neurons. Induced pluripotent stem (iPS) cell technologies offer an unprecedented opportunity to generate unlimited supplies of neurons and the facility to manipulate such cells in vitro. In this study, we developed an in vitro HSV-1 infection model in human iPS-derived neural progenitor cells (NPCs) and neurons, which displays the main hallmarks of latency defined in animal models and in humans. Induced pluripotent stem (iPS) cells were generated from human skin biopsy samples
