(Submitter supplied) Multipotent spermatogonial stem cells (mSSCs) derived from SSCs are a potential new source of individualized pluripotent cells in regenerate medicine such as ESCs. We hypothesized that the culture-induced reprogramming of SSCs was mediated by a mechanism different from that of iPS, and was due to up-regulation of specific pluripotency-related genes during cultivation. Through a comparative analysis of expression profile data, we try to find cell reprogramming candidate factors from mouse spermatogonial stem cells. more...

(Submitter supplied) Spermatogonial stem cells (SSCs) can spontaneously dedifferentiate into embryonic stem cell (ESC)-like cells, which are designated as multipotent SSCs (mSSCs), without ectopic expression of reprogramming factors. SSCs express key OSKM reprogramming factors at some levels, and do not require ectopic expression of any gene for the acquisition of pluripotency during reprogramming to mSSCs. Therefore, we reasoned that additional factors are required to regulate SSC reprogramming. 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) Reprogramming of somatic cells is a valuable tool to understand the mechanisms of regaining pluripotency and further opens up the possibility of generating patient-specific pluripotent stem cells. Reprogramming of mouse and human somatic cells into pluripotent stem cells, designated as induced pluripotent stem (iPS) cells, has been possible with the expression of the transcription factor quartet Oct4 (also known as Pou5f1), Sox2, c-Myc, and Klf4. 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) 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) While the reprogramming factors OCT4, SOX2, KLF4, and MYC (OSKM) can reactivate the pluripotency network in terminally differentiated cells, they also regulate expression of non-pluripotency genes in other contexts, such as the mouse primitive endoderm. The primitive endoderm is an extraembryonic lineage established alongside the pluripotent epiblast in the blastocyst, and is the progenitor pool for extraembryonic endoderm stem (XEN) cells. more...

(Submitter supplied) Induced pluripotent stem cells (iPSC), which are generated from a patient’s own cells and used to produce transplantable tissues, may particularly benefit older patients who are more likely to suffer from degenerative diseases. However, iPSC generated from aged donors (A-iPSC) exhibit higher genomic instability, defects in apoptosis, and a blunted DNA damage response compared to iPSC generated from younger donors (Y-iPSC). more...

(Submitter supplied) C/EBPα induces transdifferentiation of B cells into macrophages at high efficiencies and enhances reprogramming into induced pluripotent stem cells (iPSCs) when co-expressed with Oct4, Sox2, Klf4 and Myc (OSKM). However, how C/EBPα accomplishes these effects is unclear. We now found that transient C/EBPα expression followed by OSKM activation induces a 100 fold increase in iPSC reprogramming efficiency, involving 95% of the cells. more...
