Vertebrates present different types of gastrulation depending on:
- The shape of the embryo.
- The segmentation mechanism.
- The distribution of yolk.
In the case of human embryos, the process of gastrulation occurs by invagination, also called gastrulation by emboly.
Invagination is the process by which the cells of the inner cell mass (ICM) of the blastocyst fold inward and migrate into the blastocoel, giving rise to the first two embryonic layers: the ectoderm and the endoderm.
In addition to gastrulation by emboly, there are other types such as gastrulation by epiboly, by ingression, by delamination, and by involution. Each of the types of gastrulation mentioned here presents particular characteristics.
