Germ layers are produced during gastrulation and are the initial tissue layers of an embryo. Sometimes they are called embryonic tissue layers. They will develop into all the different tissues and structures present in an adult animal. 1  Ectoderm is the outermost layer of cells.  Mesoderm is the middle tissue layer.
In mammals, the blastula forms the blastocyst in the next stage of development. Here the cells in the blastula arrange themselves in two layers: the inner cell mass and an outer layer called the trophoblast . The inner cell mass is also known as the embryoblast; this mass of cells will go on to form the embryo.
