WebIn amniotes (reptiles, birds, mammals) each somite is initially an epithelial sphere, composed of about 1,000–2,0000 cells, arranged around a central lumen (which contains some mesenchymal cells and extracellular matrix) and surrounded by a basal lamina of fibronectin and other extracellular matrix materials. WebThe somites form muscle, the cartilage of the ribs and vertebrae, the dermis, the notochord, blood and blood vessels, bone, and connective tissue. The endoderm gives rise to the epithelium of the digestive and respiratory systems, and the organs associated with the digestive system, such as the liver and pancreas.
WebMesenchymal cells from the mesoderm form groups called somites on either side of the neural tube. These are like tiny building blocks that will become the vertebrae. Since an embryo develops a tail that disappears as … 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.
