Histological sections of Peyer’s patches from male Wistar rats of the groups Control - CT (A), Bisphenol A - BPA (B), Bisphenol A + Selenium - BPA + Se (C) and Selenium - SE (D) submitted to immunohistochemistry technique for antigen expression. It was observed that cell proliferation was reduced in the BPA group when compared to the other groups. Ki-67 staining was intense, especially in the epithelial layer of Peyer’s patches. Scale bars: 200x magnification.
