Witryna1 lis 2024 · After implantation, the blastocoel wall is no longer a simple TE epithelium but a rigid layer of ECM proteins (Reichert’s membrane) which is sandwiched between the parietal endoderm (PaE) and the TGCs. As the embryo develops, the cavity enlarges via an unknown mechanism to accommodate the rapidly growing egg cylinder. WitrynaThe pseudo-blasts revealed significantly lower rates of endoderm formation and development to the egg cylinder than the controls after 36 and 72 hr, respectively (P < 0.05). In the TVs and NIFs, the rates of outgrowth were significantly lower than those of the controls (P < 0.05) and no egg cylinder was observed. Witryna7 sie 2024 · Upon implantation, the spherically shaped blastocyst transforms into the egg cylinder. During this process, the polar TE generates the ExE.

The TE derived portion of the egg cylinder is called the extra-embryonic ectoderm (ExE). The VE comes to envelope both the epiblast and ExE.
