title: Development of two cloned epithelial cell lines from normal adult mouse and rat ventral prostates.
abstract: Two epithelial cell lines were established, one from adult C3H mouse and one from adult Fischer rat ventral prostate. These cell lines were obtained from explant cultures, using Ham's F12 medium supplemented with HEPES, insulin, testosterone, hydrocortisone, epidermal growth factor, and 7.5% fetal bovine serum. A low concentration of trypsin and EDTA in Ca++- and Mg++-free phosphate buffer was used for passaging the cells. The rat cell line was established following implantation of prostate tissue in nude mice. These cell lines stained positively for acid phosphatase and were dependent upon epidermal growth factor for growth. Morphological studies, including electron microscopy, revealed a highly characteristic epithelial morphology of both cell lines. These cell lines have hypotetraploid chromosome number and are capable of metabolizing benzo(a)pyrene. We propose the application of these cells as models for the study of prostate carcinogenesis.
