MDSC population in patient peripheral blood. MDSC population in patient peripheral blood. A, the percentage of CD11b+CD15+ MDSCs was analyzed by flow cytometry with lymphogating on Lin−CD14−HLA-DR− cells. Gating strategy and representative FACS dot plots of patients and healthy controls are presented. B, the percentages of MDSCs were compared between healthy controls and patients before NK-cell therapy (n = 5). C, the percentages of MDSCs from cohort 6 (n = 3) were compared before (D0H0) and after (D35) MG4101 injections (n = 3). D, changes in MDSC populations were monitored for 5 weeks. Yaewon Yang et al.
