骨组织工程人工合成支架材料的研究现状

Artificial synthesized scaffold materials of bone tissue engineering

骨组织工程支架材料的研究是骨组织工程研究的关键问题之一。骨组织工程支架材料从来源上说可分为天然生物材料和人工合成的生物材料两大类,每类材料又可分为有机材料和无机材料。每种支架材料各有其优缺点,虽然现有的支架材料仅能达到理想支架材料要求的一部分,但通过优缺点的分析为组合最优化的支架提供必要的素材。对用于组织工程支架材料的陶瓷材料、聚合物类材料、天然生物衍生材料及其复合材料等研究现状进行综述。

The scaffold material is one of the most key topics about the study of bone tissue engineering. The scaffold material of bone tissue engineering is divided into natural biomaterials and artificial synthesized biomaterials. Each kind of the materials includes organic materials and inorganic materials. Each scaffold material has its virtues and shortages. Although the existing scaffold materials merely carry some effects of the ideal materials require, the optimal scaffold may be designed using the necessary evidences provided by analyzing their virtues and shortages. This article summarized the study about the tissue engineering scaffold materials, such as porcelain and ceramics material, polymers material, natural organism-derived material and composite material.
