The specific cell in your pituitary gland that makes and releases growth hormone.Somatotrophs are acidophilic cells constituting approximately 50% of anterior pituitary hormone-producing cells. They synthesize, store, and secrete growth hormone (GH) in a pulsatile pattern regulated by opposing hypothalamic signals: GHRH (stimulatory via GHRH-R/cAMP) and somatostatin (inhibitory via SSTR2/SSTR5). GH secretagogues (ipamorelin, GHRP-2, GHRP-6, MK-677) stimulate somatotrophs via GHS-R1a. Somatotroph adenomas cause acromegaly—the primary indication for somatostatin analog therapy (octreotide, lanreotide).
