Summary
Sustained growth of mouse ventral and anterior prostatic epithelial cells embedded within collagen gel matrix was achieved in a serum-free medium composed of Dulbecco's modified Eagle's medium and Ham's F12 medium, 1∶1 (vol/vol), supplemented with bovine serum albumin fraction V, epidermal growth factor, transferrin, cholera toxin, prolactin, 5α-dihydrotestosterone, cortisol, putrescine, fibroblast growth factor, and a trace element mixture. Three-dimensional growth of prostatic epithelial cells occurred inside the collagen gel matrix. This serum-free medium allowed cell growth greater than sevenfold over 10 d in culture. Tissue recombination and cell culture techniques were integrated to demonstrate that cultured cells retained prostatic characteristics. Following 10 d of culture, epithelial colonies from mouse ventral and anterior prostatic epithelial cell cultures were isolated and combined with rat fetal urogenital sinus mesenchyme and grown for 4 wk under the renal capsule of intact athymic male mice. These tissue recombinants showed distinctive prostatic histologic characteristic (alveoli and ducts lined with cuboidal or columnar epithelium surrounded by stroma). When histologic sections of recombinants were stained with the Hoechst 33258, epithelial cells of mouse origin were distinguishable from stromal cells of rat origin.
