Characterization and biocompatibility of human-like collagen-hyaluronic acid scaffold for blood vessel
类人胶原蛋白-透明质酸血管支架的性能及生物相容性

Human-like collagen (HLC) was cross-linked with hyaluronic acid by genipin in different ratio. The concentrations of hyaluronic acid in the mixture were 0,0.01%,0.05% and 0.1%. The blood vessel tubular grafts were then fabricated by freeze-drying. Microstructure,element composite,mechanical properties,cytotoxicity grade,and biocompatibility of different vascular scaffold groups were studied by scanning electron microscope (SEM),X-ray photoelectron spectroscopy (XPS),tensile test,burst pressure experiment,cy...
