Figure 1: Effects of the standardized RVS extract on the migratory activity of VEGF-stimulated HUVEC (Wound-healing test). (a) The migrated cells in window-scraped field after scratching the cell monolayer; Control. (b) The wounds closed by cell migration from the wound edge after VEGF alone. (c) VEGF plus RVS (50 μg/mL). (d) VEGF plus RVS (100 μg/mL) showing inhibitory effect on migration compared to only VEGF-treated control.
