(Submitter supplied) ES cell pluripotency is thought to be regulated in part by H3K4 methylation. However, it is unclear how H3K4 demethylation contributes to ES cell function and participates in iPS cell reprogramming. Here, we show that KDM5B, which demethylates H3K4, is important for ES cell differentiation, and presents a barrier to the reprogramming process. Depletion of Kdm5b leads to an extension in the self-renewal of ES cells in the absence of LIF. more...

(Submitter supplied) Pluripotency of embryonic stem (ES) cells is controlled in part by chromatin-modifying factors that regulate histone H3 lysine 4 (H3K4) methylation. However, it remains unclear how H3K4 demethylation contributes to ES cell function. Here, we show that KDM5B, which demethylates lysine 4 of histone H3, co-localizes with H3K4me3 near promoters and enhancers of active genes in ES cells; its depletion leads to spreading of H3K4 methylation into gene bodies and enhancer shores, indicating that KDM5B functions to focus H3K4 methylation at promoters and enhancers. more...

(Submitter supplied) We have generated “reprogrammable” transgenic mice that ubiquitously express the four Yamanaka factors in an inducible manner. Transitory induction of the transgene results in multiple teratomas emerging from a variety of organs, thus indicating that full reprogramming into iPSCs can occur in vivo. By performing bone marrow transplant experiments, we demonstrate that both hematopoietic cells, as well as non-hematopoietic cells can be reprogrammed in vivo. more...

(Submitter supplied) Epigenetic regulation of chromatin plays a critical role in controlling embryonic stem (ES) cell self-renewal and pluripotency. However, the roles of histone demethylases and activating histone modifications such as trimethylated histone 3 lysine 4 (H3K4me3) in transcriptional events such as RNA polymerase II (RNAPII) elongation and alternative splicing are largely unknown. In this study, we show that KDM5B, which demethylates H3K4me3, plays an integral role in regulating RNAPII occupancy, transcriptional initiation and elongation, and alternative splicing events in ES cells. 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...

(Submitter supplied) Somatic cell reprogramming into pluripotent stem cells induced by Oct4, Sox2, Klf4 and Myc (OSKM) occurs at low frequencies and with a considerable delay involving a stochastic phase. In contrast, transdifferentiation of B cells into macrophages induced by C/EBPα is fully efficient and initiated almost immediately. We now discovered that a pulse of C/EBPα in B cell precursors followed by OSKM expression dramatically enhances reprogramming to pluripotency, overcoming the stochastic phase. more...

(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) Changing the somatic cell transcriptome to a pluripotent state using exogenous reprogramming factors needs transcriptional co-regulators that help activate or suppress gene expression and rewrite the epigenome. Here, we show that reprogramming-specific engagement of the NCoR/SMRT co-repressor complex at key pluripotency loci creates an epigenetic block to reprogramming. HDAC3 executes the repressive function of NCoR/SMRT in reprogramming by inducing histone deacetylation at these loci. more...
