FIG. 3.

IUL TCDD exposure increases prostate smooth muscle thickness in mice exposed in adulthood to T+E₂. (A) Immunohistochemical staining was used to visualize smooth muscle alpha actin in anterior (AP), ventral (VP), dorsolateral (DLP) prostates, seminal vesicles (SV), and bladders (Bldr) of corn oil + T+E₂- and TCDD + T+E₂-exposed mice and smooth muscle thickness was measured. Results are mean ± SE of 5 mice. An asterisk indicates a significant difference (P < .05) between groups. Scale bar = 100 μm. Color image is available in the online version of the article.
