Mast Cells of the Pituitary Gland

Abstract

THERE is a marked similarity in the morphological appearance of mast cells and the parenchymatous glandular cells of the infundibular process (neural lobe) of the pituitary gland described by Gersh¹. It has been suggested by Rennels and Drager² that the parenchymatous glandular cells may play a part in the final release of the hormones of the posterior pituitary into the general circulation. Although Gray³ described mast cells in the pituitary gland of man, ox and cat, the presence of these cells seems to have been largely ignored by more recent workers.
