Figure 2

Whole mounts and histological sections from wild-type and BK5.IGF-1 transgenic mice. Whole mounts of mammary gland from 5-week-old wild-type mouse (A) and from 5-week-old BK5.IGF-1 transgenic mouse (B). H&E-stained sections of gland from virgin, adult (postpubertal) wild-type mouse (C) and from age-matched, virgin BK5.IGF-1 transgenic mouse (D). Toluidine blue staining for mast cells in wild-type (E) and BK5.IGF-1 transgenic (F) postpubertal mammary glands. Arrows in F indicate dark-staining mast cells in the transgenic gland. Blood vessels present in H&E-stained sections demonstrate increased vascularity in postpubertal mammary gland of transgenic mice (H) compared to wild-type gland (G). Original magnifications: A and B, ×1; C and D, ×10; E–H, ×40.
