Our results obtained from 1-week tumor-bearing mice suggested that due to the higher expression of CD45, CD11b, CD11c, CD49d and ICAM-1 on PB CD62Ldim neutrophils (Figure 5A), the adhesion of CD62Ldim neutrophils was stronger than that of CD62Lhi neutrophils (Figure 5B). This evidence concerns the gene ITGA4 and neoplasm.
