Response of anterior pituitary cells to culture media.
We examined the ability of four commonly used culture media to support prolactin (PRL), growth hormone (GH), and adrenocorticotropic hormone (ACTH) release, as well as the inhibitory PRL response to dopamine. After a week of primary culture, rat anterior pituitary cells from both genders were studied over a 4 hour period. Whereas ACTH secretion was similar across the various media, PRL and GH release were lessened with M199 and F10, respectively. Dopamine inhibited PRL release under all media conditions which was inconsistant with the reported lack of a dopamine effect with RPMI-1640 medium. These data confirm the postulate that media culture conditions can determine the degree of expression of constituitive phenotypes in anterior pituitary cells.
