Bivalent histone domains have been proposed to contribute to pluripotency in embryonic stem cells, suggesting an epigenetic mechanism may regulate stem cell behavior in general. Here we compare histone modifications in two other stem cells derived from the blastocyst. We show that extraembryonic ste...

The first lineage decisions during mouse development lead to establishment of embryonic and extraembryonic tissues. The transcription factor Cdx2 plays a central role by repressing pluripotency genes, such as Oct4 and promoting trophoblast fate at the blastocyst stage. Here we show that the transcri...

To characterized the changes in gene expression during the differentiation of TS cells. TS cells can be derived from two time point during embryogenesis, cell lines tested were from each of these time points. Keywords: time course TS cells derived from either E3.5 or E6.5 embryos were differentiate...

To identify whether Cdx2 or Gata3 can activate trophoblast specific gene expression when expressed in R1 ES cells. To assess the dependency of Gata3 activity on Cdx2, Gata3 was also expressed in Cdx2-null ES cells. Keywords: gene expression a fusion construct of either Cdx2 or Gata3 and the tamoxif...

Expression profiling of stem cell lines derived from the early embryo representing the trophoblast, primitive endoderm, early epiblast (inner cell mass E3.5) and late post-implantation epiblast (E5.5). Cells were grown without feeders and harvested. Comparisons were made to provide evidence of uniqu...
