The effect of TF-SB on HUVEC tube formation. HUVECs were seeded on Matrigel-coated 96-well plates and incubated in the diluted medium containing different concentrations of TF-SB for 9 h at 37°C. 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 × and observed the network-like structures. Values represent mean ± SD from three independent experiments. * p < 0.05, ** p < 0.01 compared with the control group.
