Figure 4

The percentage of CD73 expression on peripheral blood MDSCs. Both M-MDSCs (A) and PMN-MDSCs (B) from HNSCC patients expressed significant high level of CD73 than those from healthy donors with mean 8.19% vs. 2.16% (P<0.0001) and 10.76% vs. 1.19% (P<0.0001). (C) No correlation was observed between CD73+ M-MDSCs and the clinical stage. (D) The CD73+ PMN-MDSCs was specifically correlated with the clinical stage (mean 7.74%, 10.32% and 14.38% for stage I, II and III; stage I vs. III P<0.0001, stage II vs. III, P=0.029 respectively). * indicates a P value of <0.05; *** indicates a P value of <0.0001. MDSCs, myeloid-derived suppressor cells; PMN-MDSCs, polymorphonuclear myeloid-derived suppressor cells; HNSCC, head and neck squamous cell carcinoma; Health, healthy volunteers; Patients, HNSCC patients.
