title: Preliminary studies on the cultivation and characterization of mini-pig prostate epithelial cells.
abstract: Mini-pig prostate epithelial cells exhibited the unique metabolic characteristics associated with the specialized function of production and secretion of high levels of citric acid. Epithelial cell suspensions from mini-pig prostate were successfully grown in primary and secondary cultures. The cultured epithelial cells exhibited rapid proliferation reaching confluency in approximately 6 days. Growth and proliferation of fibroblasts were markedly restricted by the dominance of epithelial cell growth. Confluent cultures could be maintained for approximately 6 weeks. The epithelial cells retained their polymorphic appearance in primary and secondary cultures and exhibited the characteristic formalin-resistant acid phosphatase reaction. Testosterone stimulated mitochondrial aspartate aminotransferase (mAAT) activity and citrate production by confluent epithelial cell cultures. These initial results indicate that cultured epithelial cells derived from mini-pig prostate might be an excellent model related to human for studies of prostate biology and hormonal regulation.
