Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...

Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications ...

In the course of early embryonic development, pluripotent stem cells first give rise to three lineages or ‘germ layers’, which then generate all cell types, tissues and organs of the human body, e.g.
