In vitro formation and thermal transition of novel hybrid fibrils from type I fish scale collagen and type I porcine collagen
In vitro formation thermal transition novel hybrid fibrils type I fish scale collagen type I porcine collagen
2010/10/12
Novel type I collagen hybrid fibrils were fabricated by neutralizing a mixture of type I fish scale collagen solution and type I porcine collagen solution with a phosphate buffer saline at 28 °C. Thei...
在超临界CO2(SC-CO2)循环萃取条件下制备PLA/TCP/Collagen(PTC)多孔组织工程支架材料,研究了胶原含量对支架材料的总孔隙率、开孔率、孔洞形态和力学性能的影响,以及胶原纤维在支架材料中的分布.结果表明:用SC-CO2反复循环萃取法制备的PTC支架材料开孔率可达到82.81%,比不加胶原的PLA/TCP支架高约25%;孔径为200-500 μm,孔洞之间出现重要的"隧道"结构;...
