Figure 5From: Tissue engineering of heart valves: PEGylation of decellularized porcine aortic valve as a scaffold for in vitro recellularizationThe quantification of DNA at different time among groups and scanning electron photomicrographs of GRGDSPC-PEG-DAV-PEG-VEGF 165 group. A: Quantification of DNA in the DAV, PEG-DAV, GRGDSPC-PEG-DAV-PEG-VEGF165 groups at 4 and 8 days. Compared with DAV, *P > 0.05, **P < 0.05; compared with PEG-DAV, ΔP < 0.01 B: Scanning electron photomicrographs depicting HUVECs adhesion and proliferation on GRGDSPC-PEG-DAV-PEG-VEGF165 group after 8 days in culture (×2000).Back to article page
