- Any of several peptides that are synthesized in the liver and other tissues and are capable of stimulating growth processes, especially in bone, cartilage, and muscle. Somatomedins are secreted and activated in response to growth hormone. Somatomedin levels rise progressively during childhood, peak at puberty, and then stabilize at lower levels in adulthood.
