骨与软骨缺损的修复作为一大难题,长期以来一直困扰着骨科医生。近年来人工骨材料有了迅速的发展,其中以采用组织工程技术,将外源性生长因子转染种子细胞以组成一个相互作用的转染复合体系,从而对种子细胞进行成骨及软骨诱导,用以构建组织工 The repair of bone and cartilage defects has long plagued orthopedic surgeons as a major problem. In recent years, there has been a rapid development of artificial bone materials, in which the use of tissue engineering technology, exogenous growth factor transfection of seed cells to form an interactive transfection complex system, so that the seed cells osteogenic and cartilage induction, Used to build tissue workers
