Fig. 1. Resistin promotes MCP-1 expression in OASFs and facilitates monocyte migration. (A) OASFs were incubated with resistin (1-10 ng/ml) for 24 h; MCP-1 mRNA expression was examined by qPCR. (B) OASFs were incubated with resistin for 24 h then stimulated with MCP-1 antibody (1 μg/ml) for 30 min. The conditioned medium (CM) was then collected and applied to THP-1 cells. THP-1 migration was measured. Results are expressed as the mean ± SEM. *p<0.05 as compared with the control group; #p<0.05 as compared with the resistin-treated group.
