Figure 2: Effects of the standardized RVS extract on the tube formation in VEGF-stimulated HUVECs. (a) HUVECs seeding in Matrigel form capillary networks; Control. (b) The robust and complete tube network formation after VEGF alone. (c) VEGF plus RVS (50 μg/mL). (d) VEGF plus RVS (100 μg/mL) showing inhibitory effect on tube network formation compared to only VEGF-treated control.
