Epiblast

From Wikipedia, the free encyclopedia

In embryology, the epiblast is a class of cells present during gastrulation. It is one of two types of cells arising from the inner cell mass, but only epiblast cells give rise to the three germ layers of the embryo. Together, epiblast and hypoblast comprise the bilaminar disk of the developing embryo.

In Mammalian embryogenesis, the columnar cells of the epiblast are adjacent to the trophoblast, while the cuboidal cells of the hypoblast are closer to the Blastocoele.
