title: Immunoelectron microscopic observation of prolactin (PRL) in human PRL secreting pituitary adenomas and non-neoplastic pituitary PRL cells.
abstract: Immunoelectron microscopic localization of prolactin (PRL) was studied in pituitary adenoma cells and in non-neoplastic PRL cells. The adenoma cells showed characteristic concentration of PRL in Golgi region which was ultrastructurally in Golgi saccules and in vesicular RER. In contrast, the non-neoplastic PRL cells showed lamellated RER which contained PRL. These results suggested disproportional production of PRL and its secretion in the adenoma cells.
