TNF-α enhanced migratory ability of RAECs. (A) Migration was detected using a Transwell assay (magnification, ×100). (B) Compared with the control group, the migratory ability of RAECs was significantly increased in the TNF-α conditioned medium group. A concentration of 10 ng/ml TNF-α was used for the migration analysis. The control group was incubated in endothelial cell medium. Data are presented as the mean ± standard deviation of 6 individual samples of independent triplicate experiments. *P<0.05 vs. control group. RAECs, rat aortic endothelial cells; TNF-α, tumor necrosis factor-α.
