Transcriptome analysis during somatic cell reprogramming

ABSTRACT: By combining deep sequencing with high-throughput quantitative RT-PCR, we reveal that somatic splicing profiles are reorganized to pluripotent splicing profiles during reprogramming from mouse embryonic fibroblasts (MEFs) to induced pluripotent stem (iPS) cells. The splicing pattern in pluripotent stem cells resembles that in testis, and the regulatory regions have specific characters in length and sequence. These results indicate that the dynamic alteration in splicing is an integral part of the molecular network involved in the reprogramming process.

Sequencing data from MEF, two iPS cell lines and one ES cell line. RT-PCR data will be represented within Figures or Tables in published manuscripts.

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.

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.

Generation of Induced Pluripotent Stem Cells from Adult Rhesus Monkey Fibroblasts

Project description:Induced pluripotent stem (iPS) cells can be generated from somatic cells by transduction with several transcription factors in both mouse and human. However, direct reprogramming in other species has not been reported. Here, we established an efficient method to generate monkey iPS cells from fibroblasts by retrovirus-mediated introduction of the four monkey transcription factors OCT4 (POU5F1), SOX2, KLF4, and c-MYC. The monkey iPS cells displayed ES-like morphology, expressed ES cell-marker genes, shared similar global gene profiles and methylation status in the OCT4 promoter to those of monkey ES cells, and possessed the ability to differentiate into three germ layers in vitro and in vivo. Our results suggest that the mechanism of direct reprogramming is conserved among species. The efficient generation of monkey iPS cells will allow investigation of the feasibility of therapeutic cloning in primate model with various diseases. Keywords: Induced pluripotent stem, iPS, Rhesus monkey We analysed each sample (Rhesus monkey fibroblast, embryonic stem cell (ES) and induced pluripotent stem cell (iPS)) for three replications and sought to see high similarty between iPS and ES.

Comparisons between fully and partially reprogrammed iPS cells induced by pMX-Klf4, pMX-Oct4 and pMX-Sox2 retroviruses

Project description:Induced pluripotent stem (iPS) cell reprogramming is a gradual epigenetic process that reactivates the pluripotent transcriptional network by erasing and establishing heterochromatin marks. Here, we characterize the physical structure of heterochromatin domains in full and partial mouse iPS cells by correlative Electron Spectroscopic Imaging (ESI). In somatic and partial iPS cells, constitutive heterochromatin marked by H3K9me3 is highly compartmentalized into chromocenter structures of densely packed 10 nm chromatin fibers. In contrast, chromocenter boundaries are poorly defined in pluripotent ES and full iPS cells, and are characterized by unusually dispersed 10 nm heterochromatin fibers in high Nanog-expressing cells, including pluripotent cells of the mouse blastocyst prior to differentiation. This heterochromatin reorganization accompanies retroviral silencing during conversion of partial iPS cells by Mek/Gsk3 2i inhibitor treatment. Thus, constitutive heterochromatin reorganization serves as a novel biomarker with retroviral silencing for identifying iPS cells in the very late stages of reprogramming. We compared the expression profiles of partially and fully reprogrammed iPS cell lines derived from CD1 mouse embryonic fibroblasts (MEFSs) by retroviral reprogramming (pMX-Oct4, pMX-Klf4 and pMX-Sox2). to the differentiated MEFS and the J1 embryonic stem cell line. We also studied the effect of a 2i cocktail treatment in partially reprogrammed iPS cells.

Genome-wide mapping of miRNAs expressed in embryonic stem cells and pluripotent stem cells generated by different reprogramming strategies

Project description:We report the miRNA profiling in MEF cells, ES cells and three Pluripotent Stem Cells obtained by three different reprogramming approaches from MEF cells based on Solexa sequencing. iPS cells are reprogrammed by four factors (OSKM) from MEF cells. NT-ESCs were established by reprogramming MEF cells into ESCs using nuclear transfer. NT-iPSCs were established to reflect the combination of nuclear transfer and iPS technologies. iPSCs, NT-ESCs, and NT-iPSCs were exactly derived from the same MEF cells. The results indicate NT-ESCs give expression to the unique miRNAs other than both ESCs and iPSCs while pluripotent cells acquire or retain the pluripotent specific miRNAs compared with MEF. Furthermore, the comparison of different reprogramming cells suggests that several miRNAs have key roles in distinctly developmental potential reprogrammine cells. Small RNA profiles of MEF, ES, iPS, NT-ES and NT-iPS cells were generated by Solexa sequencing. MEF and ES cells were performed in triplicate. iPS, NT-ES and NT-iPS cells were sequenced in duplicate.

Global gene expression profiles of iPSC from SMA patient, unaffected father and iPS 19.9 compared to transcriptomic data obtained by corresponding fibroblasts

Project description:Spinal Muscular Atrophy (SMA) is an autosomal recessive motor neuron disease and is the second most common genetic disorder leading to death in childhood. Motoneurons derived from induced pluripotent stem cells (iPS cells) obtained by reprogramming SMA patient and his healthy father fibroblasts, and genetically corrected SMA-iPSC obtained converting SMN2 into SMN1 with target gene correction (TGC), were used to study gene expression and splicing events linked to pathogenetic mechanisms. Microarray technology was used to assess global gene expression profiles of iPSC from SMA patient, unaffected father and iPS 19.9 (Prof. J. Thomson's lab) compared to transcriptomic data obtained by corresponding fibroblasts. The microarray data derived from three different individuals: SMA patient, healthy father and control iPS cells (19.9). We analyzed iPSC from SMA patient (n=2), iPS- from healthy father (n=1) and iPS-19.9 from Prof. Thomson's lab (n=3). The expression profile was compared to SMA patient's fibroblasts (n=2) and healthy father's fibroblasts (n=1)
