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.
