Fig. 1.

Examples of uterine morphology and collagen accumulation in uterus of control (A–C), 30 ppm BPA (D–F) or 0.01 ppm EE (G–I) exposure groups at PND90. Shown are photomicrographs of H&E and picrosirius red-stained uterine sections from similar uterine locations in each panel. In panel D a region of uterus with abnormal pathology is shown. Arrows are indicating an example of a developing gland nest structure. These structures were observed at a low frequency in all groups. Exposure related changes in picrosirius red-staining indicating alterations of collagen accumulation were not apparent. Scale bars represent 50 µm.
