Figure 2From: Sustained release of VEGF from PLGA nanoparticles embedded thermo-sensitive hydrogel in full-thickness porcine bladder acellular matrix Proliferation of HUVEC cells was induced by 10 ng/mL free-VEGF, or 20 ng/mL free-VEGF, or 10 ng/mL VEGF in NPs, or 20 ng/mL VEGF in NPs, or non-loaded NPs (NL-NPs) at the same concentration of PLGA with the application described above, and compared to culture medium alone (control) for 1-5 days. Y-axis represents fold increase versus control. Asterisk represents P < 0.05 and double asterisk represents P < 0.01.Back to article page
