Histological sections of Peyer’s patches from male Wistar rats from the groups Control - CT (A), Bisphenol A - BPA (B), Bisphenol A + Selenium - BPA + Se (C) and Selenium - SE (D). No BCL-2 markings were observed in the Peyer patches of the groups studied, except in the BPA + Se group. Scale bars: 200x magnification.
Masson’s special trichrome staining technique revealed a differentiation between the immune cells that make up Peyer’s plaques and the connective tissue belonging to it (Figure 5).
