The importance and the requirements of tissue engineering scaffold are introduced briefly, and characteristics of bioactive ceramics, natural polymer and synthetic polymers for tissue engineering scaffolds are reviewed. The principles of electrospinning, thermally induced phase separation, solvent casting/particulate leaching and freeze-drying for preparing the scaffold are introduced in detail. Finally, existing main problems in this field are presented and the future research considerations are discussed.%简述了组织工程支架的重要性及要求,综述了制备组织工程支架所用生物活性陶瓷、天然高分子及合成高分子材料的特点,着重介绍了静电纺丝法、热致相分离法、溶剂浇铸/粒子沥滤法和冷冻-干燥法制备组织工程支架的原理,提出了组织工程支架研究存在的问题,并展望了组织工程支架未来的研究方向.
