(Submitter supplied) Differentiated cells can be reprogrammed into induced pluripotent stem cells (iPSCs) following the forced overexpression of a specific combination of transcription factors, of which Oct4 is essential. To better understand the mechanism underlying iPSC reprogramming, we investigated the immediate transcriptional response to ectopic Oct4 expression in somatic cells. To this end, we derived different somatic cell types from Oct4-inducible transgenic mice and induced Oct4 expression for different time periods. more...

(Submitter supplied) Nr5a2 (also known as liver receptor homolog-1, Lrh-1) has been shown to bind both the proximal enhancer and proximal promoter regions of Pou5f1 and regulate Pou5f1 in the epiblast stage of mouse embryonic development (Gu et al., 2005). Nr5a2-null embryos display a loss of Oct4 expression in the epiblasts (Gu et al., 2005) and die between E6.5 and E7.5 (Gu et al., 2005; Pare et al., 2004). To identify the targets of Nr5a2, we generated a stable ES cell-line that expresses HA-tagged Nr5a2. more...

(Submitter supplied) Low Klf4 expression reproducibly gives rise to a homogeneous population of partially reprogrammed iPSCs. Upregulation of Klf4 allows these cells to resume reprogramming, indicating that they are paused iPSCs that remain on the path towards pluripotency. Paused iPSCs with different Klf4 expression levels remain at distinct intermediate stages of reprogramming.

(Submitter supplied) Resolution of early molecular events preceding endogenous OCT4 activation is critical to understanding the mechanism of reprogramming somatic cells to induced pluripotent stem cells (iPSCs), yet capturing transient regulators at the onset of reprogramming is difficult in heterogeneous populations of asynchronously reprogramming fibroblasts following four-factor transduction. To address this need, we used a heterokaryon system to identify an early and transiently expressed homeobox transcription factor, NKX3-1. more...

(Submitter supplied) We used heterokaryon cell fusion based reprogramming and identified the cytokine IL6 as a potential regulator of reprogramming to pluripotency. We generated iPS clones using the four reprogramming factors (4F) Oct4, Klf4, Sox2, and c-Myc. In addition, iPS clones were generated using only three factors (3F: Oct4, Klf4, amd Sox2) with the addition of the cytokine IL6 to reprogramming culture conditions. more...

(Submitter supplied) Oct4 is widely considered the most important among the four Yamanaka reprogramming factors. Here we show that the combination of Sox2, Klf4, and cMyc (SKM) suffices for reprogramming mouse somatic cells to induced pluripotent stem cells (iPSCs). Simultaneous induction of Sox2 and cMyc in fibroblasts triggers immediate retroviral silencing, which explains the discrepancy with previous studies that attempted but failed to generate iPSCs without Oct4 using retroviral vectors. more...

(Submitter supplied) The success of Yamanaka factor reprogramming mouse embryonic fibroblasts (MEFs) into induced pluripotent stem cells (iPSCs) suggests that some factor(s) must remodel the nuclei from a condensed state to a relaxed state to facilitate factor binding to target genes. We asked how the Yamanaka factor-dependent chromatin opening occurs. We found Oct4, but neither Sox2 nor Klf4, is responsible for the loosening of the condensed state. more...

(Submitter supplied) Reprogramming of somatic cells produces induced pluripotent stem cells (iPSCs) that are invaluable resources for biomedical research. Transcriptional and epigenetic changes have been investigated to facilitate our understanding of the reprogramming process. Here, we extended the previous transcriptome studies by performing RNA-seq on cells defined by a combination of multiple cellular surface markers. more...

(Submitter supplied) Klf4 and Sox2 are among the core reprogramming factor, and have different function in reprogramming. Klf4 is supposed to trigger MET in the early stage of reprogramming ,Sox2 is well known plutipotent relative gene. Klf4 and Sox2 play important role in induced reprogramming. We performed this experiment to identify the targets regulated by Sox2 and Klf4 respectively.
