(A) Net speed of microvascular endothelial cells quantified as start position to end position over the time of the experiment. Time lapse image acquisition occurred every 15 mins over a 16 hour period. * p < 0.05 vs. VEGF group, n=6 wells per group over 3 experiments. (B) Effect of treatment groups on dispersed microvascular endothelial cell proliferation, VEGF n=19 wells, VEGF+Hcy, VEGF+Hcy+1400W, and VEGF+1400W n=22 wells.
