esodermo 20
The mesoderm is one of the three embryonic leaves or cell layers constituting the embryo. Training can be done by enterocoely or schizocoely from a blastocyst in the process called Gastrulation. Prior to the formation of the mesoderm and the Gastrulation process, there are two layers, the hypoblast and epiblast. The epithelial cells of the epiblast are transformed into accommodating migrant mesenchymal cells, are invaginan and give rise to the 3 embryonic layers, pushing the hypoblast to the yolk sac epithelium.
