Cell cycle of HUVECs after 24 h of treatment, as detected by flow cytometry. 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. The percentage of cells in the G0/G1, S, and G2/M phases are indicated on the upper right side. I: The percentage of cells residing in the G0/G1, S, and G2/M phases. The data are expressed as the mean ± SD. Significant differences compared with controls are presented (*p < 0.05).
