X-chromosome inactivation is established during early development. In mice, transcriptional repression of the paternal X-chromosome (Xp) and enrichment in epigenetic marks such as H3K27me3 is achieved by the early blastocyst...
During pre-implantation development, the mammalian embryo self-organizes into the blastocyst, which consists of an epithelial layer encapsulating the inner-cell mass (ICM) giving rise to all embryonic tissues. In mice, oriented...
The precise relationship of embryonic stem cells (ESCs) to cells in the mouse embryo remains controversial. We present transcriptional and functional data to identify the embryonic counterpart of ESCs. Marker profiling shows...
