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.
This means that they have three different germ layers. In between the endoderm and the ectoderm is a layer called the mesoderm. Each of these tissue layers will develop into different adult structures. For example, in humans: 1  Ectoderm: develops into your nervous system (brain and spinal cord) and outer skin layer.iploblastic animals have a gastrula with only ectoderm and endoderm layers. Triploblastic animals have a gastrula with ectoderm, endoderm, and mesoderm layers. These embryonic tissue layers will eventually develop into all the different tissues and structures found in an adult animal.
