Representation of H&E-stained slides of the formalin-fixed, paraffin-embedded prostate tissues from prostate-specific antigen-transgenic mice of different ages. (A) Representative example of normal prostate tissue harvested from a 4-week-old mouse with no evidence of inflammation. (B) and (C) Representative photomicrographs of prostate sections from a 15- and 24-month-old mouse, respectively, at different magnifications. An aggregate of chronic inflammatory cells is noted in (B), and in (C) diffuse chronic inflammation in the stroma (right upper corner) and glandular degeneration.
