The proportion of CD66b+CD10+ in the peripheral blood of healthy volunteers is 99.6 ± 0.4%, and that of CD66b+CD10– was 0.4 ± 0.2% (Figure 2A); The proportion of CD66b+CD10+ in the peripheral blood of sepsis patients was 90.2 ± 13.5%, and the proportion of CD66b+CD10– was 10.3 ± 3.9% (Figure 2A), which was significantly different from that of healthy volunteers (P < 0.001) (Figure 2B). Here, MME is linked to Sepsis.
