The mesoderm that lies on either side of the vertebrate neural tube forms a set of temporary structures called somites (also called “primitive segments”), shown below. Later in development the cells within the somites will migrate to different parts of the body to develop into bone, skeletal muscle, and connective tissue of the skin.
In vertebrate patterning establishing body axes is a critical step in animal development. During mouse embryonic development, nodal a transforming growth factor-beta superfamily ligand, is a key gene involved in patterning both the anterior-posterior axis and the left-right axis of the early embryo.
