|Abstract:||Folliculo-stellate cells of adenohypophysis were studied by transmission electron microscopy in lactating rats during treatment with the dopaminergic agonist 2-bromo-alpha-ergocriptine. Folliculo-stellate cells showed marked activation in control lactating rats, were unaffected by a single injection of the drug (3 mg/kg), regressed to the morphology of those found in non-lactating animals upon 6 days of drug treatment (1 mg/kg/die) both in presence and in absence of the suckling stimulus. However, morphometric analysis showed a proportion of folliculo-stellate cells in the gland which was similar in the four experimental groups (range: 11.3-13.5%), despite the increasing reduction of prolactin cells (55, 44, 32, 30%). In chronically treated animals to which suckling had been denied, extruding and degenerating prolactin cells were found, as well as extracellular material in non follicular spaces; the latter were lined by both folliculo-stellate and endocrine cells. These data suggest a dual reactivity of folliculo-stellate cells in the adenohypophysis according to the functional status of the gland.|
