BALB/cJ mice have more tuberoinfundibular dopamine neurons, and thus greater tyrosine hydroxylase activity, than CBA/J mice. Strain differences in the synthesis and release of prolactin would also be predicted since dopamine released from the tuberoinfundibular neurons is the prolactin inhibitory factor which plays a role in the regulation of both prolactin synthesis and release. As expected, CBA/J mice, with fewer dopamine neurons, synthesized and released significantly more prolactin than BALB/cJ mice; that is, both pituitary and serum prolactin concentrations were greater in CBA/J mice. To determine if there were more cells containing prolactin or more prolactin per cell, pituitaries were stained with antibodies to prolactin and densitometric analysis made of both the average staining per unit area and total staining per pituitary. For both indices CBA/J mice had more staining than BALB/cJ mice. Using these criteria the difference in staining was attributed to more prolactin-stained lactotrophs in the CBA/J strain. Although no differences in the number of acidophils demonstrated by Pearse Trichrome method were observed, acidophils from BALB/cJ mice appeared smaller and contained less cytoplasm than those from CBA/J mice. We conclude that strain differences in the number of tuberoinfundibular dopamine neurons are inversely related to the number of immunocytochemically demonstrable prolactin-containing cells in the anterior pituitary.
