Effect of Rg1 on HUVEC tube formation. In total, 1 × 105 HUVECs were seeded on Matrigel-coated 48-well culture plates and treated with released Rg1, standard Rg1, or VEGF. After 8 h, tubular structures were photographed (100 ×). 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 tube formation was compared with tube formation in the control group (untreated). Photographed by microscope at 100 ×. The data are expressed as the mean ± SD. Significant differences compared with controls are presented (*p < 0.05).
