Somatotropin

Somatotropin, also known as growth hormone (GH), is a peptide hormone that is responsible for stimulating physical growth along with cell reproduction and regeneration both in humans and animals. The type of mitogen that it possesses is specific only to certain kinds of cells and is synthesized, stored, and secreted by somotropic cells that are located within the lateral (side) wings of the anterior pituitary gland. Additionally, it functions as a stress hormone that raises the concentration of glucose and free fatty acids in the blood stream.
