摘要: 丝素蛋白因其具有良好的生物相容性、生物可降解性以及卓越的力学性能而被广泛应用于组织工程。为了促进丝素支架更利于细胞的黏附和增殖、促进新的细胞外基质生成、组织向内生长以及利于营养物质及代谢产物的运输等,丝素支架微观结构的构建仍是组织工程的一个重大挑战。本文着重围绕丝素支架的微观结构展开,介绍了多孔结构、纤维结构、多孔-纤维结构和水凝胶结构近年来在组织工程中的应用,从不同支架结构制备方法及功能方面并结合作者实验相关工作对比分析了不同支架结构的优势和存在的问题以及对细胞的影响,指出应从分子水平及原子水平上研究天然组织的结构来精准、有效地体外模拟构建组织工程丝素支架。

Abstract: Silk fibroin has excellent biocompatibility,biodegradability,and remarkable mechanical properties,which have made silk fibroin widely applied in tissue engineering (TE). However,it is still a challenge to fabricate the architecture of tissue engineering scaffolds with the purpose of promoting cellular migration,attachment,formation of new extracellular matrix and tissue ingrowth and fostering the transport of nutrients and metabolic wastes. In this work,the microcosmic architectures of TE silk fibroin scaffolds,mainly including porous,fibrous,porous-fibrous and hydrogel architectures,are discussed and summarized by comparing different scaffold structures and their effects on cells referring to our works. Furthermore,we consider that it is necessary to pay further attention on the molecular and atomic structures of the nature tissues to mimic them precisely in vitro.

Key words: silk fibroin, scaffold, microcosmic, architecture, tissue engineering
