The Correlation between PSCA Expression and Neuroendocrine Differentiation in Prostate Cancer

Figure 1

PSCA and NSE protein expression in different patients’ prostate cancer lesions using immunohistochemistry. (A1) (IHC score: 1; IHC grade: 0) and (A2) (IHC score: 0; IHC grade: 0) are from the same patient’s prostate cancer tissue; (B1) (IHC score: 9; IHC grade: 3) and (B2) (IHC score: 6; IHC grade: 2) are from the same patient’s prostate cancer tissue; (C1) (IHC score: 7; IHC grade: 2) and (C2) (IHC score: 6; IHC grade: 2) are from the same patient’s prostate cancer tissue. Abbreviations: PSCA: prostate stem cell antigen; NSE: enolase 2.
