Acidophils produce prolactin and growth hormone. The acidophil is known as a chromophil_cell, which means it is a cell that readily acquires stain. Acidophils have a dark nucleus and pink/red cytoplasm.
Basophils produce the tropic (trophic) hormones, including adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), Follicle-stimulating hormone (FSH), and lutenizing hormone (LH). Basophils are also chromophil cells. Basophils have a dark blue nucleus and cytoplasm.
Chromophobes are still under investigation. Electron microscope studies have revealed that they have active secretory granules. Recent information suggests they may be degranulated chromophil cells. The nucleus of a chromophobe acquires dark blue stain, but the cytoplasm remains clear or a very sheer, pale blue.
