Presence of High Affinity Dopamine Receptors in Estrone-Induced, Prolactin-Secreting Rat Pituitary Adenomas: A Model for Human Prolactinomas

Adenomatous cells obtained from a pituitary tumor induced in Fisher 344/Lis rats by the subcutaneous implantation of estrone (E1) were found to secrete large amounts of prolactin (PRL). The
