The endoderm is one of the germ layers formed during animal embryogenesis. Cells migrating inward along the archenteron form the inner layer of the gastrula, which develops into the endoderm. The endoderm consists at first of flattened cells, which subsequently become columnar.
1 The 3 germ layers-the ectoderm, the mesoderm, and the entoderm (endoderm): are in place at the end of gastrulation. The entoderm development is simpler than that of either mesoderm or ectoderm. 2  It is a monocellular layer lining the yolk sac until cephalocaudal flexion of the embryo takes place. 3  Flexion takes the embryo from a flat disk to its basic embryonic body form.
