BMDMs were cultured on an uncoated surface, fibrinogen-coated surface, or TG2-cross-linked fibrinogen coated surface for 4 hours then stimulated with 1 ng/mL lipopolysaccharide (LPS) for 6 or 24 h. IL-10 (A), TNFα (B), IL-1β (C), and IL-6 (D) were measured in supernatant using enzyme-linked immunosorbent assay (ELISA), n=4–8. *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001
