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.
