Abstract

Angiogenesis is a process requiring a coordinated guidance from multiple factors. We examined the effects of angiogenic endothelial cell sprouting under the gradient of soluble factors, VEGF and ANG-1. This resulted in a different cellular morphology than the condition with single factors; the presence of VEGF gradient induced a greater number of tip cells, and addition of ANG-1 to the VEGF gradient stabilized collectively migrating cells. Interestingly, as shown by the average filopodial angle measured, tip cell was affected by VEGF only when ANG-1 gradient was not present, possibly because the tip cells attached to stalk cells have reduced freedom.
