Isolation and culture of rat seminal vesicle epithelial cells. The use of the secretory protein SVS IV as a functional probe.
A method for the isolation and culture of seminal vesicle epithelial cells obtained from control and androgen-primed sexually-immature, uncastrated rats is described. This method allows the establishment of monolayer cultures from aggregates of seminal vesicle epithelial cells isolated after trypsin and collagenase digestion. Phase contrast and transmission electron microscopic methods demonstrate that cell aggregates, after attaching to the substrate, establish within 48 h a colony-like, epithelial-like growth pattern. Immunofluorescent localization studies of SVS IV, an androgen-dependent secretory protein purified from rat seminal vesicle secretion, show that cultured seminal vesicle epithelial cells are immunoreactive. An electrophoretic analysis of [35S]methionine-labeled secretory proteins immunoprecipitated with rabbit anti-SVS IV serum demonstrate that, whereas SVS IV is newly-synthesized and accumulated in the medium of cultured seminal vesicle cells established from androgen primed rats, cultured cells from control rats appear to synthesize and accumulate SVS IV in a precursor form. Results of this work show that seminal vesicle epithelial cells in culture not only retain several structural features representative of the tissue but also serve as a potential system for the study of androgen action.[1]References
