主 题:RGD peptide graphene oxide poly(lactic-co-glycolic acid) biofunctional scaffold vascular smooth muscle cell
摘 要:In recent years,much research has been suggested and examined for the development of tissue engineering scaffolds to promote cellular *** our study,RGD peptide and graphene oxide(GO)co-functionalized poly(lactide-co-glycolide,PLGA)(RGD-GO-PLGA)nanofiber mats were fabricated via electrospinning,and their physicochemical and thermal properties were characterized to explore their potential as biofunctional scaffolds for vascular tissue *** electron microscopy images revealed that the RGD-GO-PLGA nanofiber mats were readily fabricated and composed of randomoriented electrospun nanofibers with average diameter of *** successful co-functionalization of RGD peptide and GO into the PLGA nanofibers was confirmed by Fourier-transform infrared spectroscopic ***,the surface hydrophilicity of the nanofiber mats was markedly increased by co-functionalizing with RGD peptide and *** was found that the mats were thermally stable under the cell culture ***,the initial attachment and proliferation of primarily cultured vascular smoothmuscle cells(VSMCs)on the RGD-GO-PLGA nanofibermats were *** was revealed that the RGD-GO-PLGA nanofibermats can effectively promote the growth of *** conclusion,our findings suggest that the RGD-GO-PLGA nanofiber mats can be promising candidates for tissue engineering scaffolds effective for the regeneration of vascular smooth muscle.
