title: [Comparative ultrastructural study of the epithelial stromal junction in the prostatic gland].
abstract: In this paper, the authors carry out a comparative study of the structures adjacent to the alveolar periphery of the prostate-glands of men, dogs and bulls. In the three cases an E.S.J. (Epithelial-Stromal-Junction) similar to that described in the mammary gland and characterized in the first two cases by the existence of four, ultrastruct strata, consisting of the basal lamina, the somas of the adjacent fibroblasts and their cytoplasmic expansions as well as the arrangement of the intercellular, collagen microfibrils, was found to exist in this gland. In the case of the bovine prostate gland, the structural organization of the E.S.J. was basically characterized by the structural arrangement of the collagen microfibrils. The structures described constitute models on which to base future research on the hyperplastic and neoplastic processes of the prostate gland.
