Fig. 9. Mammary glands from MMTV/TβRI(AAD) transgenic mice display a dramatic reduction in epithelial content and sparse lobulo-alveolar structures during pregnancy and lactation. (Left) Whole-mount analyses conducted on control (FVB/N) and transgenic (AAD) mice at different stages during mammary gland development and involution. Scale bars represent 0.5 cm. (Right) Histological analyses were performed by hematoxylin and eosin (H&E) staining on control (FVB/N) and transgenic (AAD) mice at different stages of mammary gland development and involution. Scale bars represent 200 μm (large image) and 50 μm (Inset). The arrows indicate the region of each H&E section that is magnified in Inset.
