Table 2 Fibrillar collagen content of mammary glands

From: Tamoxifen induces pleiotrophic changes in mammary stroma resulting in extracellular matrix that suppresses transformed phenotypes

Grade of collagen depositiona Control group Tamoxifen group
Grade I 5 (23%) 0 (0%)
Grade II 12 (54%) 9 (38%)
Grade III 5 (23%) 15 (62%)
  1. aGrade I glands are at least 50% adipocyte-rich stroma and devoid of dense fibrillar collagen deposition. Grade II glands have moderate levels of dense fibrillar collagen or areas with mixed collagen densities and Grade III glands have at least 50% of glands filled with dense fibrillar collagen deposition.
