WebA spatial pattern of gene expression reorganizes the mesoderm into groups of cells called somites with spaces between them. The somites, illustrated in Figure 24.29 will further develop into the ribs, lungs, and segmental (spine) muscle. The mesoderm forms at the same time as the other two germ layers, the ectoderm and endoderm. The mesoderm at either side of the neural tube is called paraxial mesoderm. It is distinct from the mesoderm underneath the neural tube, which is called the chordamesoderm that becomes the notochord. The paraxial mesoderm is initially called the "segmental plate" in the chick emb…
