Dys and Eureprogramming

ABSTRACT: Pluripotent stem cells have the potential to differentiate in vitro in many, if not all, functional cell types. Induced pluripotent stem cells (iPS) have recently emerged as a reproducible model of pluripotent stem cells that can be generated from post-natal tissues. To understand this process at the transcriptome level, we generated iPS cell lines, partially reprogrammed cell lines and compared their transcriptome with that of the partental human foreskin fibroblasts and human embryonic stem cell lines.

Project description:Pluripotent stem cells have the potential to differentiate in vitro in many, if not all, functional cell types. Induced pluripotent stem cells (iPS) have recently emerged as a reproducible model of pluripotent stem cells that can be generated from post-natal tissues. To understand this process at the transcriptome level, we generated iPS cell lines, partially reprogrammed cell lines and compared their transcriptome with that of the partental human foreskin fibroblasts and human embryonic stem cell lines. Four categories of samples, comprising human foreskin fibroblasts, fully reprogrammed iPS cell lines, partially reprogrammed iPS cell lines and human embryonic stem cell lines were compared using Significance Analysis of Microarrays (SAM). These data were also compared to a compendium of differentiated human samples and a pluripotency classifier was computed.

Transcription profiling of mouse differentiated, partially- and fully-reprogrammed MEFs/B-cells

Project description:Expression profiles generated during dissection of the molecular mechanisms underlying direct reprogramming of somatic cells to a pluripotent state (induced pluripotent stem cells, iPS). Experiment Overall Design: 2 technical replicates of B lymphocytes, partially reprogrammed (MCV8, MCV6, BIV1), MEF-iPS(Oct4) and B-iPS(Nanog) cell lines.

Generation of pluripotent stem cells

Project description:Pluripotent stem cells, which are capable to generate any cell type of the human body, such as human embryonic stem cells (hESC) or human induced pluripotent stem cells (hiPS) are a very promising source of cells for regenerative medicine. However, the genesis, the in vitro amplification and the differentiation of these cells still need improvement before clinical use. This study aimed to improve our knowledge on these critical steps in pluripotent stem cell generation. We derived new hESC lines, generated hiPS and compared these cell types with human foreskin fibroblasts and partially reprogrammed fibroblasts. We included in the overall study hESC, hiPS, human foreskin fibroblasts and partially reprogrammed fibroblasts. Here, hESC lines derived from embryos were hybridized on U133 Plus 2.0 GeneChips (Affymetrix). All samples were normalized using the MAS5 (GCOS 1.2) algorithm, using the default analysis settings and global scaling as normalization method, with a trimmed mean target intensity value (TGT) of each array arbitrarily set to 100. Human pluripotent stem cells were compared with somatic samples and partially reprogrammed cells.

Molecular insights into induced pluripotency mediated by the OCT4, SOX2, KLF and c-MYC gene regulatory network

Project description:Human somatic fibroblasts can be reprogrammed to induced pluripotent stem (iPS) cells by exogenic expression of the Yamanaka factors (OCT4, SOX2, KLF4 and MYC) after about 1 month. To gain some insight into the early processes operative in fibroblast reprogramming, we profiled genome-wide transcription levels using Illumina microarrays in the starting donor cells-human foreskin fibroblast (HFF1) cells and at three time points after OSKM transduction (24 h, 48 h, 72 h), as well as two iPS cell lines (iPS2, iPS4) and hES cell lines (H1, H9). We show that within the context of the viral transduction reprogramming protocol, the donor cell response to viral transfection perturbs redox homeostasis, which induces oxidative damage on the donor cells' protein and DNA. This leads to activation of p53, senescence, and apoptosis, greatly reducing the efficiency of reprogramming. Total RNA obtained from HFF1 (human foreskin fibroblast) cells, OSKM-transduced HFF1 cells after 24h, 48h, 72h, undifferentiated hESCs, iPSCs.

Inducible iPS Cells Support Full-term Development of Tetraploid BlastocystâComplemented Embryos

Project description:Differentiated somatic cells can be reprogrammed into induced pluripotent stem (iPS) cells by forced expression of four transcription factorsâOct4, Sox2, Klf4, and c-Myc. However, it remains undetermined whether the reprogrammed iPS cells are fully pluripotent, resembling normal embryonic stem (ES) cells, given that no iPS cell lines have been shown to possess the capability to autonomously generate full-term mice after injection into tetraploid blastocysts. Here, we provide evidence demonstrating that iPS cells induced by the four transcription factors can be fully pluripotent and that full-term mice can be produced from complemented tetraploid blastocysts. This work serves as a proof of principle that iPS cells can generate full term embryos by tetraploid complementation. We compared the gene expression profile of iPS cell, ES cell and MEF. ES cell and MEF served as control for iPS cell. Three biological repeats were included for each line.

Inducible iPS Cells Support Full-term Development of Tetraploid Blastocyst–Complemented Embryos

How C/EBPa creates an elite cell state for reprogramming to pluripotency

Project description:Mouse B cells, upon ectopic expression of the transcription factor C/EBPalpha for 18h, can be reprogrammed to induced pluripotent stem (iPS) cells with extremely high efficiency. To understand the molecular control of this phenomenon we performed a time course proteomic analysis by label-free protein quantification of proteins during B cell reprogramming to iPS cells.

X-chromosome inactivation in monkey embryos and pluripotent stem cells

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.
