The anterior pituitary gland comprises five types of secretory cells, arranged in nests and cords. These cells are distinguished by histochemical and immuno-cytochemical staining, and by electron microscopic appearances, into: Somatotrophs: GH Lactotrophs: PRL Thyrotrophs: TSH Gonadotrophs: LH and FSH Corticotrophs: ACTH
Somatotrophs and lactotrophs are acidophilic, while thyrotrophs, gonado-
trophs and corticotrophs are basophilic. Furthermore, there are inactive secretory cells called chromophobe cells.
