Fig. 1From: Overexpression of CXCR7 accelerates tumor growth and metastasis of lung cancer cellsCXCR7 and CXCR4 expression in lung tumor tissue. a. Lung tumor samples were subjected to immunohistochemical staining for CXCR7(upper) and CXCR4(lower) expression, para-tumor tissue as normal control (n = 4) (Magnification: 200×). b. Lung tumor tissue and para-tumor tissue were lysed and analyzed for CXCR7 and CXCR4 expression by western blot. β-actin was used as a loading control (n = 2)Back to article page
