BMDMs were cultured on an uncoated surface, fibrinogen-coated surface, or TG2-cross-linked fibrinogen-coated surface for 4 hours then stimulated with lipopolysaccharide (LPS) for the indicated time points. (A) Tnfa and (B) Il10 expression was measured in BMDMs treated with 1 ng/mL LPS for 30, 60, or 120 min via qRT-PCR. Data are presented as mean fold induction + SEM compared to vehicle-treated BMDMs on an uncoated surface at t=0 (not shown) (n=3–11). (C) TNFα, (D) IL-6, and (E) IL-10 protein levels were measured in supernatant following stimulation of BMDMs with 1 ng/mL LPS for two hours (n=7–13). *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001
