The Germ layers consist of about three layers of cells:
- Ectoderm – exterior germ layer
- Mesoderm – middle germ layer
- Endoderm – internal germ layer
These three distinct layers are formed after a blastocyst’s inner cell mass undergoes a process of specific organization called gastrulation,(21963156) which occurs after the blastocyst phase in embryonic development.
Organization or Gastrulation (22804578) involves many things including distinct differentiation patterns in human mesenchymal cell motility, cell shape, and cell adhesion.(22775353)
