Cell migration occurs extensively during both gastrulation and organogenesis.
Cell migration occurs extensively during gastrulation and organogenesis. During gastrulation three germ layers are formed. The Ectoderm, mesoderm and Endoderm are formed and these are positioned by the migration of epithelial and mesenchymal cells. During organogenesis organs are formed by the germ layers.
