To characterize the phenotypes of the epithelium in PCaT and normal prostate tissue and in derived early and late PCCs and PDOs, we assessed the expression of basal (CK5, p63) and luminal (CK18, AR1) epithelial markers and prostate cancer markers (AMACR and EZH2) by RT-PCR. Here, AMACR is linked to prostate carcinoma.
