Histology of ventral prostates from 5-month-old BERKO vs. wild-type mice. (A–C) Hematoxylin/eosin staining of a fixed section from the peripheral zone of a wild-type mouse prostate (A) and similar staining of fixed sections from the peripheral (B) and central (C) zones of a BERKO mouse prostate. Hyperplastic foci in the BERKO prostate are indicated with arrows. (Higher magnification of each section is depicted in a lower corner of each picture.) (Thick horizontal bars = 50 μm; thin bars = 200 μm.)
