Figure 4From: Differential expression of decorin, EGFR and cyclin D1 during mammary gland carcinogenesis in TA2 mice with spontaneous breast cancerExpression of PCNA in mammary glands and spontaneous breast cancer tissues from TA2 mice. PCNA staining could be observed in the nuclei of epithelial cells from five month-old TA2 mice (4A) and spontaneous breast cancer-bearing TA2 mice (4B) (IHC, 400×). PCNA staining was present in the nuclei of spontaneous breast cancer cells from TA2 mice (4C) (IHC, 400×).Back to article page
