(Submitter supplied) Nodal and Activin are morphogens of the TGFbeta superfamily of signaling molecules that direct differential cell fate decisions in a dose- and distance-dependent manner. During early embryonic development the Nodal/Activin pathway is responsible for the specification of mesoderm, endoderm, node and mesendoderm. In contradiction to this drive towards cellular differentiation, the pathway also plays important roles in the maintenance of self-renewal and pluripotency in embryonic and epiblast stem cells. more...

(Submitter supplied) Epiblast stem cells (EpiSC) are pluripotent stem cells derived from mouse postimplantation embryos between E5.5 to E7.5, a time window in which gastrulation commences. Therefore, EpiSC represent a valuable tool for studying mammalian postimplantation development in vitro. Beyond their pluripotent features, EpiSC can also be reprogrammed into a mouse embryonic stem cell-like (mESC) state. Published reports showed that EpiSC reversion requires transcription factor overexpression, while others suggest that applying stringent mESC culture conditions alone was sufficient to revert EpiSC to mESC-like cells. more...

(Submitter supplied) Epiblast stem cells (EpiSCs) were derived from the epiblast or the ectoderm (epi/ect) of pre-gastrula stage to late-bud stage mouse embryos. To identify if the EpiSCs retain any original stage specific characteristics or which developmental stage of epi/ect they most closely related to, we performed microarray analysis to compare the gene expression profile of multiple EpiSC lines with that of epi/ect of 7 different stages.

(Submitter supplied) We compared the transcriptomes of EpiSCs maintained in the presence or absence of Wnt pathway inhibitor IWP2. We screened also our gene expression data for potential markers for genuine EpiSCs, maintained in the presence of Wnt inhibition and compared with ESC expression data. We compared the transcriptomes of EpiSCs maintained in the presence or absence of IWP2. The high level of Wnt-induced differentiation occurring in conventional EpiSC cultures may have interfered with the analysis of their characteristics. more...

(Submitter supplied) Activin/Nodal/TGF-β signaling pathway plays a major role in maintaining mouse epiblast stem cells (mEpiSCs). The mEpiSC medium which contains Activin A and bFGF induces differentiation of mouse embryonic stem cells (mESCs) to mEpiSC. Here we show that Activin A also has an ability to efficiently propagate mESCs without differentiation to mEpiSCs when combined with a MEK inhibitor PD0325901. mESCs cultured in Activin+PD retained high-level expression of naive pluripotency-related transcription factors. more...

(Submitter supplied) The combination of Wnt pathway activation by the GSK3 inhibitor and ERK pathway inhibition by the MEK inhibitor, which is known as 2i is a well-established method to maintain mouse embryonic stem cell (mESC) self-renewal. Here we show that Activin A also has the ability to promote naive pluripotency of mESCs when combined with the MEK inhibitor PD0325901. mESCs were efficiently propagated in a medium containing both Activin A and the MEK inhibitor (PD0325901). more...

(Submitter supplied) Activin/Nodal signalling is necessary to maintain pluripotency of human Embryonic Stem Cells (hESCs) and to induce their differentiation towards endoderm. However, the mechanisms by which Activin/Nodal signalling achieves these opposite functions remain unclear. To unravel these mechanisms, we examined the transcriptional network controlled in hESCs by Smad2 and Smad3 which represent the direct effectors of Activin/Nodal signalling. more...

(Submitter supplied) We reported H3K4me3, H3K27ac and H3K27me3 histone modification in EpiSCs and Nodal inhibited EpiSCs(EpiSCS/F). Using ChIP sequencing, we demonstrate that the active modification of H3K4me3 and H3K27ac level are higher in EpiSCS/F, suggesting EpiSCsS/F were in an active chromatin state. Interestingly, H3K27me3, the supressive modification enriched more in EpiSCS/F down regulated genes, suggesting H3K27me3 plays pivital roles in regulating gene expression.
