Lipopolysaccharide (LPS) promoted RAW 264.7 M1 polarization. (a): LPS 500 ng/ml stimulated RAW264.7 for 12, 24, 48 and 72 hours, the level of IL-6 significantly increased in a time-dependent manner. (b, c): Flow cytometry showed LPS enhanced the expression of M1 macrophages at all time points. *** P<0.001 compared with control group
