(Submitter supplied) Genome wide comparison of gene expression between EpiSC lines derived from fertilized (FT) embryos and somatic cell nuclear transfer (NT) embryos. EpiSC lines were derived from fertilized and somatic cell nuclear transfer embryos and cultured until 15 to 20 passages. RNA was then extracted in order to compare transcriptomic profiles.

(Submitter supplied) Genomic imprinting, resulting in parent-of-origin specific gene expression, plays a critical role in mammalian development. Here, we perform allele-specific RNA-Seq on isogenic B6D2F1 mice to assay imprinted genes in tissues from early embryonic stages and in pluripotent cell lines. For the cell lines, we include embryonic stem cells (ESCs) and epiblast stem cells (EpiSCs) derived from fertilized embryos or from embryos obtained after nuclear transfer (NT), as well as B6D2F1 ESCs and EpiSCs derived after parthenogenetic activation (PGA). more...

(Submitter supplied) During early mammalian development transient pools of pluripotent cells emerge that can be immortalised upon stem cell derivation. The pluripotent state, "naïve" or "primed", depends on the embryonic stage and derivation conditions used. Here we analyse the temporal gene expression patterns of mouse, cattle and porcine embryos at stages that harbour different types of pluripotent cells. We document conserved and divergent traits in gene expression, and identify predictor genes shared across the species that are associated with pluripotent states in vivo and in vitro Amongst these are the pluripotency-linked genes Klf4 and Lin28b The novel genes discovered include naïve- (Spic, Scpep1 and Gjb5) and primed-associated (Sema6a and Jakmip2) genes as well as naïve-to primed transition genes (Dusp6 and Trip6). more...

(Submitter supplied) Primitive ectoderm cells (PE) in blastocysts represent the foundation of the pluripotent state, which is lost progressively during development. For example, development of epiblast cells from PE in postimplantation embryos is accompanied by transcriptional and epigenetic changes, including DNA methylation and X inactivation (Refs); these changes alter the nature of epiblast cells fundamentally, affecting their responsiveness to signaling molecules, and constitute a robust boundary that prevents their reversion to a PE-like state. more...

(Submitter supplied) Embryonic stem cells (ESCs) comprise at least two populations of cells with divergent states of pluripotency. Here, we show that epiblast stem cells (EpiSCs) also comprise two distinct cell populations that can be distinguished by the expression of a specific Oct4-GFP marker. These two subpopulations, Oct4-GFP positive and negative EpiSCs, are capable of converting into each other in vitro. Oct4-GFP positive and negative EpiSCs are distinct from ESCs with respect to global gene expression pattern, epigenetic profile, and Oct4 enhancer utilization. more...

(Submitter supplied) Pluripotent stem cells provide a platform to interrogate control elements that function to generate all cell types of the body. Despite their utility for modeling development and disease, the relationship of mouse and human pluripotent stem cell states to one another remains largely undefined. We have shown that mouse embryonic stem (ES) cells and epiblast stem cells (EpiSCs) are distinct, pluripotent states isolated from pre- and post-implantation embryos respectively. more...

(Submitter supplied) Embryonic Stem Cells (ESCs) and Epiblast Stem Cells (EpiSCs) are the in vitro representants of naïve and primed pluripotency, respectively. It is currently unclear how their epigenome underpin the phenotypic and molecular characteristics of these states of pluripotency. Here, we performed the first qualitative and quantitative comparison of DNA methylation between ESCs and EpiSCs. The global level and genomic distribution of DNA methylation were very similar between the two cell types. more...

(Submitter supplied) Blimp1 (Prdm1), the key determinant of primordial germ cells (PGC), plays a combinatorial role with Prdm14 during PGC specification from postimplantation epiblast cells. They together initiate epigenetic reprogramming in early germ cells towards an underlying pluripotent state, which is equivalent to embryonic stem cells (ESC). Whereas Prdm14 alone can promote reprogramming and is important for the propagation of the pluripotent state, it is not known if Blimp1 is similarly involved. more...

(Submitter supplied) Embryonic stem cells (ESCs), which are derived from the primitive ectoderm of pre-implantation blastocysts, are pluripotent cells and can thus contribute to the formation of all somatic cell lineages in chimeric animals. Similarly, epiblast stem cells (EpiSCs), which are derived from epiblast tissue of post-implantation embryos, are also pluripotent and can give rise to derivatives of all three germ layers in teratoma assays. 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) Epiblast stem cells (EpiSCs) derived from post-implantation epiblast are pluripotent stem cells, epigenetically distinct from embryonic stem cells (ESCs), which are widely used in reprogramming studies. Recent achieved haploid cell lines in mammalian open a new era for high-throughput genetic screening, due to their homozygous phenotypes. Here, we report the generation of mouse haploid EpiSCs (haEpiSCs) from post-implantation embryos at embryonic day 6.5 (E6.5). more...

(Submitter supplied) We utilized FAIRE-seq to identify accesible chromatin in mouse embryonic-, epiblast-, and neural- stem cells in addition to mouse embryonic fibroblasts. Analysis of these data sets reveal cell type specific chromatin signatures that differentiate naïve and primed pluripotency. Functional analysis of type-specific peaks revealed cell-type specific enhancers.

(Submitter supplied) Mouse naïve pluripotent stem cells (ESC) can contribute to all embryonic tissues and the germline, but rarely to the extra-embryonic tissues in chimeric embryos. Here we describe a novel advanced pluripotent stem cell (ASC) with higher potency, since a single ASC contributes very efficiently to the fetus, germline, yolk sac and the placental labyrinth in chimeras. ASCs were derived from blastocysts in two steps in a chemically defined medium with Activin A (ActA) and basic fibroblast growth factor (bFGF), followed by Wnt and BMP. 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.

(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...
