摘要:: Experimentation with the progenitor/stem cells in adult prostate epithelium can be inconvenient due to a tight time line from tissue acquisition to cell isolation and to downstream experiments. To circumvent this inconvenience, we developed a simple technical procedure for culturing epithelial cells derived from human prostate tissue. In this study, benign prostate tissue was enzymatically digested and fractionated into epithelium and stroma, which were then cultured in the medium designed for prostate epithelial and stromal cells, respectively. The cultured cells were analyzed by immunocytochemical staining and flow cytometry. Prostate tissue-regenerating capacity of cultured cells in vitro was determined by co-culturing epithelial and stromal cells in dihydrotestosterone-containing RPMI. Cell lineages in formed acini-like structures were determined by immunohistochemistry. The culture of epithelial cells mainly consisted of basal cells. A minor population was negative for known lineage markers and positive for CD133. The culture also contained cells with high activity of aldehyde dehydrogenase. After co-culturing with stromal cells, the epithelial cells were able to form acini-like structures containing multiple cell lineages. Thus, the established culture of prostate epithelial cells provides an alternative source for studying progenitor/stem cells of prostate epithelium.
