Figure 2: Developmental BPS and EE2 exposures alter adult mammary gland morphology including the retention of TEBs.

Figure 2:

A) Whole mount mammary gland collected from females in early adulthood (9 weeks of age). Arrows indicate terminal ends, arrowheads indicate alveolar buds. Scale bar = 0.5mm. B) Quantification of alveolar buds in adult mammary glands. C) Quantification of terminal ends. D) Quantification of all epithelium. E) Examples of normal terminal ends (arrowheads) and TEB-like structures (arrows) in adult mammary glands. In all panels, * p < 0.05, Bonferroni posthoc after significant ANOVA. Sample sizes: control = 23; 2 μg BPS/kg/day = 16; 200 μg BPS/kg/day = 13; 0.01 μg EE2/kg/day = 16; 1 μg EE2/kg/day = 11.
