From: Effect of bisphenol A on morphology and apoptosis in the mammary gland of adult Wistar rats
a In mammary gland (bar = 100 μm), the stromal connective tissue further recedes (arrow) and the alveolar buds progressively increased in the control group. H&E, × 200. b In mammary gland of 5 mg treated (bar = 100 μm), the alveolar buds increased and connective tissue recedes (arrow). H&E, × 200. c The epithelial of ducts does not show positive staining, but stromal tissue (arrow) shows faint positive staining in control group of the mammary gland (bar = 50 μm), × 400. d The epithelial of ducts does not show positive staining, but stromal tissue (arrow) shows faint positive staining in 5 mg BPA-treated group of the mammary gland (bar = 50 μm), × 400
