重組人甲狀旁腺素(7-34)背景: Polypeptide hormones secreted by the parathyroid glands， which promote release of calcium from bone to extracellular fluid by activating osteoblasts and inhibiting osteoclasts， indirectly promote increased intestinal absorption of calcium， and promote renal tubular reabsorption of calcium and increased renal excretion of phosphates. It is a major regulator of bone metabolism. Secretion of parathyroid hormone increases when the level of calcium in the extracellular fluid is low. Its action is opposed by calcitonin.
PTH （7-34）， which is a PTH/PTHrP receptor antagonist， can stimulate hair growth and epidermal proliferation in mice.
