Effect of the released Rg1 on HUVEC migration. Observation of the effect of the released Rg1 on HUVEC migration after 24 h using a Transwell culture insert. A: Control group (untreated); B: 0.1 μg/ml released Rg1; C: 1 μg/ml released Rg1; D: 10 μg/ml released Rg1; E: 50 μg/ml released Rg1; F: 100 μg/ml released Rg1; G: 50 μg/ml standard Rg1; and H: 20 ng/ml VEGF. I: The percentage increase in HUVEC migration was compared with migration in the control group (untreated). Photographed by microscope at 200 × .The data are expressed as the mean ± SD. Significant differences compared with controls are presented (*p < 0.05).
