[Primary culture of prostatic adenocarcinoma: a model for studies of stromal-epithelial interactions].

Abstract

Primary culture of prostatic adenocarcinoma is obtained from surgical material after radical prostatectomy. Typing of the obtained culture with antibodies to vimentin and cytokeratins has shown that the proportion of basic cell components--stromal and epithelial--in vitro correlates with such in the initial tumor tissue. In cultivation in different media active migration and proliferation of all cell types in the presence of embryonal serum and suppression of the stromal component in the medium where the serum was replaced for bovine hypophysis extract were observed. A comparative immunohistochemical analysis registered a release into culture of alpha SMA-positive myofibroblasts and active expression of TGF beta-1 in the medium containing serum. Design of dynamic mixed cell systems may serve a convenient model for investigation of stromal-epithelial interactions and their changes in cancer progression.
