Adenocarcinoma of the prostate comprises 95% of all prostate cancer. Commercially available primary cultures of "normal" prostate epithelial cells, PrECs, have been used as a convenient model to investigate neoplastic transformation. Here PrECs were characterized for the expression of lineage- and developmental-specific markers cytokeratin (CK) 8 and 18, p63, chromogranin A, TMEPAI, S100P, NKX 3.1, ANKH, and FN 1 as well as androgen receptor and prostate-specific antigen by Western blot and Northern blot analyses, immunohistochemistry, reverse transcriptase-polymerase chain reaction (RT-PCR), and quantitative real-time PCR. Immunohistochemical staining detected PrECs positive in varying degrees for p63, CK 8, and CK 18, with only the rare cell being positive for chromogranin A. The PrECs also tested positive for p63 protein by Western blot analysis. RT-PCR with PrEC cDNA showed products for FN 1 and S100P but not for ANKH and androgen receptor or prostate-specific antigen. This profile of markers in PrEC cells is consistent with that expected for pubertal prostate epithelial cells.
