title: Immunohistochemical detection of folliculo-stellate cells in human pituitary adenomas.
abstract: In the light of recent findings concerning the presence of S-100 antigen in folliculo-stellate cells of the rat adenohypophysis, we investigated the possible presence of S-100-labelled cells in both the normal human adenohypophysis and in pituitary adenomas. Immunostaining enabled us to detect, with both light and electron microscopy, the presence of S-100-labelled folliculo-stellate cells in a significant number of pituitary adenomas, mostly growth-hormone secreting, and, as expected, in the normal human adenohypophysis.
