In vitro induction of MDSCs by recombinant IL-35 or IL-27, with or without the combination of GM-CSF and IL-6. Isolated PBMCs were cultured in vitro for 5 days. GM-CSF and IL-6 were added in the medium as positive controls. Classic flow cytometric charts (A) and statistical results (B) showed that IL-35 with or without GM-CSF and IL-6 effectively induced MDSCs, while IL-27 had no remarkable effects. (C) Representative flow cytometry charts of NO production using the DAF-DM diacetate staining. (D) Statistical results of flow cytometry analysis on NO produced by MDSCs. (E) Representative histograms of ROS production in different treatment groups. (F) Statistical analysis of mean fluorescence intensity (MFI) of ROS in different treatment groups. *p < 0.05, **p < 0.01, ***p < 0.001.
