表面修饰对羟基磷灰石修复骨缺损的影响

Effect of HA surface modification on repairing bone defect
摘要
精氨酸-甘氨酸-天冬氨酸（Arg-Gly-Asp,RGD）多肽是介导种子细胞与支架材料黏附的多肽链．RGD序列可被固有黏附蛋白受体特异性结合．在生物材料表面自发形成一分子层．为与受体介导的种子细胞提供特异性位点而促进细胞的黏附和分化。笔者旨在应用RGD多肽对羟基磷灰石（hydroxyapatite．HA）材料进行表面修饰处理．以促进骨髓基质干细胞（marrow stromal cells．MSC）在其表面的黏附和生长．为骨组织工程提供一种支架材料的表面修饰手段。
