Genetic Polymorphism and Expression of CXCR4 in Breast Cancer

Figure 4

CXCR4 protein expression in breast tumor tissue samples. CXCR4 immunoreactivity was observed in the cytoplasm of tumor epithelial cells. Representative micrograph result for positive CXCR4 staining: (a) weak staining = 1, (b) moderate staining = 2, and (c) strong staining = 3.
