| 摘 要： | 组织工程的目标之一就是制备出能引导细胞分化并产生具有一定功能再生组织的支架材料,支架材料生物功能化能够有效促进细胞的生物活动,是组织再生的关键。本文从提高支架材料生物功能化入手,说明纳米材料是蛋白和细胞吸附的最佳选择,重点分析了化学改性、引入RGD多肽片断、多肽-聚合物支架及ECM基支架材料四种提高支架材料生物功能化的方法,并对支架材料生物功能化的未来发展趋势进行了展望。

| Abstract: | The major goal of tissue engineering is to produce the scaffold that can induce cells to adhesion,proliferation and differentiation in its surface,and finally to repair the tissue or make the tissue regeneration.The scaffold biofunctionality is the key issue to the tissue regeneration,which can improve the cell bioactivity.In this paper,we focus on the biofunctionality of scaffold and state the nano-structure is advantage for protein absorption and cell adhesion in the surface of scaffold.Four research meth... |
