Meanwhile, no significant difference in the percentage of CD11b+Gr-1+ MDSCs was observed in either the tumor tissues (43.90 ± 2.22 vs. 46.15 ± 1.46 vs. 46.50 ± 1.967%, P = 0.4452, P = 0.4306) or spleens (41.03 ± 1.72 vs. 43.90 ± 1.76 vs. 42.93 ± 0.65%, P = 0.3093, P = 0.3603) of the three groups (Figure 3B). This evidence concerns the gene ITGAM and neoplasm.
