PTPRC and neoplasm: While Neo- and M7-tumoring bearing mice showed a similar percentage of 7/4+CD11b+Ly6G+ neutrophils in CD45+ leukocytes in the tumors and spleens (Figure 4A and B), there was a significantly higher proportion of Ly6Ghigh neutrophils in the tumors (p < 0.001) and the spleens (p = 0.017) of M7 tumor-bearing mice (Figure 4C and D).
