Effects of TF-SB on the cell migration of HUVECs. Cell migration was analyzed by the scratch assay. HUVECs were treated with various concentrations of TF-SB (40, 80 and 120 μg/mL) for 48 h. A: blank control group; B: 40 μg/mL TF-SB group; C: 80 μg/mL TF-SB group; D: 120 μg/mL TF-SB group. The images were captured under a phase-contrast microscope at a magnification of 100×. Values represent mean ± SD from three independent experiments. ^* p < 0.05, ^** p < 0.01 versus the control group.
