ASPN and NT5E expression in cribriform prostate cancer. (A) Representative images of dual ASPN (blue) and NT5E (red) mRNA expression in stroma adjacent to benign prostate (n = 9), Gleason grade 3 prostate cancer (n = 6), Gleason grade 4 prostate cancer without cribriform morphology (n = 6), and Gleason grade 4 prostate cancer with cribriform morphology (n = 6) (×400 magnification). (B) The percentage of NT5E
+ stromal cells adjacent to benign prostate, Gleason grade 3 prostate cancer, Gleason grade 4 prostate cancer without cribriform morphology, and Gleason grade 4 prostate cancer with cribriform morphology. (C) The relative expression of NT5E in NT5E
+ stromal cells. (D) The mean NT5E H‐score. (E) The percent ASPN
