Lactotrophs (also known as lactotrope, mammatroph, mammotroph, epsilon acidophil, prolactin cell, and lactotropic cell) are cells in the anterior pituitary which produce prolactin in response to signals including dopamine and estrogen.

If these cells undergo neoplastic transmormation, they will give rise to a prolactinoma, a prolactin-secreting pituitary adenoma.
