"Witryna1 sty 2012 · The formation of the egg cylinder from the late blastocyst occurs as a result of rapid proliferation of cells of the epiblast and overlying TE, causing them to grow into the blastocyst cavity. 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. " - Implantation and formation of egg cylinder

Witryna1 sty 2003 · After implantation, rapid growth of the epiblast and ExE leads to the formation of the egg cylinder, with the dorsal-ventral axis of the future embryo already apparent. Although cells of the epiblast remain uncommitted until around the time of gastrulation, their patterning and differentiation are also specified by cell position ( … 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.
