inner cell mass
Transcription precedes loss of Xist coating and depletion of H3K27me3 during X chromosome reprogramming in the mouse inner cell mass
... Together, our RNA FISH and allele-specific RT-PCR results show that reactivation of seven Xp-linked genes occurs in the presence of Xp-Xist coating. In order to determine the broader transcriptional status of the Xp, we ...

Mouse chimaeras developed from electrofused blastocysts: new evidence for developmental plasticity of the inner cell mass
... The mammalian egg is radially symmetrical around the animal- vegetal axis. Site of the extrusion of the polar bodies designates the animal pole of this axis. In the mouse, the early blastocyst is radially symmetrical ...
