Witryna1 lut 1981 · The initiation of mouse egg-cylinder formation in vivo occurs soon after implantation due to the development of a multilayered extraembryonic ectodermal tissue from the previously single layer of polar trophectoderm ( Snell & Stevens, 1966; Gardner & Johnson, 1975; Gardner & Papaioannou, 1975; Copp, 1979 ). Witryna11 mar 2024 · During the peri-implantation stages, the mouse embryo radically changes its appearance, transforming from a hollow-shaped blastocyst to a tube-like conceptus (egg cylinder). The core of the egg cylinder is composed of a fluid-filled cavity, whose function and mechanism of formation have been elusive so far.

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).
