Phyllanthus emblica L. Enhances Human Umbilical Vein Endothelial Wound Healing and Sprouting
Figure 5
Effects of PE and ASC on endothelial sprouting. Evaluation of in vitro model of spheroid angiogenesis was performed 24 h after spheroids were embedded in the collagen matrix containing vehicle (CTRL), VEGF 100 ng/mL (VEGF), PE (0.1, 1, and 10 μg/mL), and ascorbic acid (ASC: 0.01, 0.1, and 1 μg/mL). Cumulative sprout length per spheroid was determined using an image program as described in Section 2. (a) to (i) are representative photographs of spheroids with different treatments indicated in the figure; (j) bar graph demonstrates cumulative sprout length of all the treatments. versus control.
