Figure 2From: Differential expression of decorin, EGFR and cyclin D1 during mammary gland carcinogenesis in TA2 mice with spontaneous breast cancerExpression of EGFR in mammary glands and spontaneous breast cancer tissues from TA2 mice. 2A, EGFR staining could be observed occasionally in epithelial cells in mammary gland tissues from five-month-old TA2 mice (IHC, 200×). 2B and 2C, EGFR staining was localized to both the cytoplasm and nucleus in mammary gland tissues from spontaneous breast cancer-bearing TA2 mice (IHC, 200×). 2D, Nuclear EGFR was also present in spontaneous breast cancer tissues from TA2 mice (IHC, 200×). Mammary gland tissues and tumor tissues from cancer-bearing TA2 mice expressed higher levels of EGFR than those of mammary gland tissues of five-month-old TA2 mice.Back to article page
