WebNov 17, 2013 · During gastrulation, a ball of cells transforms into a two-layered embryo made of an inner layer of endoderm and an outer layer of ectoderm. In more complex … During the third week, a process called gastrulation creates a mesodermal layer between the endoderm and the ectoderm. This process begins with the formation of a primitive streak on the surface of the epiblast. The cells of the layers move between the epiblast and the hypoblast, and begin to spread laterally and cranially. The cells of the epiblast move toward the primitive streak and slip beneath it, in a process called "invagination".

WebA germ layer is a layer of cells that will go on to form one of our organizational tubes. Our anatomy can really be boiled down to an inner tube (our digestive tract), and a series of tubes that wrap around it. The three germ layers that will translate into these tubes are the ectoderm, the mesoderm, and the endoderm. Weband the hypoblast /primitive endoderm. During the ingression mesodermal cells turn off the cell adhesion molecule Cadherin, a general property of epithelial to mesenchymal transitions. On the outside, the primitive endoderm will ultimately be enclosed in the developing gut, from which it gets the name visceral endoderm. 5.The mesoderm …
