Temporal regulation of soluble VE-cadherin from endothelialized gene-free scaffold and SDF-1α GAS. SDF-1α GAS strongly affects the vascular growth of endothelial cells by suppressing the release of soluble VE-cadherin. Coculturing with ADSCs offers further control on the release of soluble VE-cadherin from endothelial cells. HUVECs on SDF-1α GAS demonstrated significant reduction in the levels of soluble VE-cadherin at days 7 (p < 0.05) and 10 (p < 0.0005) relative to HUVECs on gene-free scaffold. Coculture on SDF-1α GAS strongly attenuated the release of VE-cadherin at all time points. Data are presented as mean ± standard deviation. One-way ANOVA was used to deduce statistical significance. *, **, ***, and **** indicate statistical significance of p < 0.05, p < 0.01, p < 0.005, and p < 0.0005, respectively
