Immunohistochemical analysis of tumors formed by Cl66 cells in wild type and Cxcr2−/− mice for proliferation and angiogenesis: a and b Quantification of PCNA (a) and CD31 (b) staining. Five fields were counted from each tumor for PCNA and CD31 positive cells (n = 5). The mean was calculated and mean ± SEM was graphed for each group. Significant differences are represented with p values. c and d Microscopic images of representative tumor sections from wild type or Cxcr2−/− mice showing PCNA and CD31 staining
