摘要:

背景:静电纺丝是一种制备组织工程支架材料极有前途的技术手段。
目的:综述目前静电纺丝技术在组织工程中的应用进展及其在应用中存在的主要问题。
方法:应用计算机检索Medline数据库、中国知网数据库2000至2013年文章,检索关键词为“静电纺丝,组织工程;Electrospinning,tissue engineering”。
结果与结论:静电纺丝技术制备的纳米纤维无纺布材料,其结构类似于细胞外基质,具有高的比表面积,可控机械性能良好,便于加工,已被广泛应用到组织工程中生物降解材料和高分子聚合物的合成领域。静电纺丝在组织工程中的应用进展快速,尤其所选用的电纺材料或者与不同技术结合的电纺。静电纺丝能将材料的性能与组织的不同形态结构相结合,一系列新的聚合物被成功引入到组织工程支架中作为细胞再生和增殖的基质,然而重要的问题是,如何控制支架与生物系统的相互作用即实现细胞的浸润性生长,如何控制孔隙大小,机械性能,毒性等,在该技术应用到真正实用的生物医学中之前仍然需要进一步研究,尤其是体内研究。

Abstract:

BACKGROUND: Electrospinning preparation for the tissue engineering scaffold materials is an extremely promising technology.
OBJECTIVE: To review the progress of electrospinning technology in different fields and its main problems in the current application.
METHODS: We searched Medline and CNKI databases for articles published from 2000 to 2013 using the keywords of “electrospinning, tissue engineering” in English and Chinese.
RESULTS AND CONCLUSION: The structure of non-woven cloth materials made by this technology is similar to the extracellular matrix, which has high surface area and controllable mechanical properties. Electrospinning materials have been widely applied in the tissue engineering field, especially in the biodegradable materials and high biocompatibility molecular polymer synthesis process. Electrospinning has been developed rapidly in tissue engineering applications, especially in the choice of materials or electrospinning technique combined with different technologies. Different morphological structures and properties of the materials can be well combined by using electrospinning technology. A series of new polymers were successfully incorporated into a tissue engineering scaffold as the matrix for cell proliferation and regeneration, but there are some important issues to be solved, including how to control the interaction between the scaffold and the biological system that is to achieve the infiltrative growth of cells, how to control the pore size, mechanical properties and toxicity. This technology clinically applied in biomedicine still requires further research, especially in vivo studies.
