PADS stimulate HUVEC migration. a. HUVEC migration was assessed 16 h after seeding in the top chamber of Matrigel-coated Boyden chambers in minimal media and supplementing the bottom chamber minimal media with ELP, VEGF, or VEGFPADS at the indicated concentrations. b. Average cells per field were counted for four to seven fields per sample. Data represent the mean ± se of three independent experiments. *p = 0.002, one-way ANOVA with post-hoc Bonferroni multiple comparison.
