Deposition of collagen (blue) in mammary glands of rats stained with Masson's Trichrome. In glands with the lactating phenotype (A) and increased number of acini (C and D), collagen was found surrounding larger ducts (arrowheads) and not associated with acinar structures (arrows); this pattern was also evident in positive control lactating mammary gland (B). Collagen surrounded DCIS structures (E) and was found within the carcinoma (F). Ducts containing sloughed epithelial cells showed more collagen deposition surrounding the duct (G) than that seen in normal tissue (H). Scale bar: 50 μm
