Fig. 2. Contact-dependence of B-cell suppression by M-MDSCs.

Fig. 2

Assays were performed as in Figure 1, specifically for the co-cultures (with contact). In addition: (A) M-MDSCs (upper well) were physically separated from responder cells (lower well) using a transwell system (see Materials and Methods). (B) A Griess’ assay was performed with stimulated B-cells (lower well) co-cultured with M-MDSCs (upper well) in the absence of cell contact. Data shown are from representative experiments, with a similar pattern of results (as shown for both A and B) observed in at least 5 experiments each. Significance levels: *, p<0.05; **, p<0.01; NS, not significant.
