文题释义:
微图案技术:是一种小型化图案的方法,最初用于电子学领域,近年来已成为生物材料工程和细胞生物学基础研究的一种基本研究方法,它通常使用光刻和软光刻的方法,但目前已经开发了许多其他技术。
微图案技术对细胞图案化的方式:一是通过在嗜细胞和疏细胞区域表面化学修饰细胞黏附蛋白,并接种细胞,使细胞随机被动地图案化;二是通过光辅助、电刺激、机械载荷甚至直接打印的方法将细胞沉积在基底表面上,形成精准的细胞微图案。
 
 
背景:随着微图案技术的不断创新和发展,其在细胞生物学、组织工程和再生医学等相关研究中也有着更加广泛的应用,为体外构建人工组织提供了新的动力。
目的:总结并讨论微图案技术的分类、特点及其在组织工程中的应用。
方法:检索2001至2017年Web of Science数据库、PubMed数据库及中国知网与微图案技术及其在组织工程中应用相关的文献,英文检索词为“micro-pattern technique,tissue engineering”,中文检索词为“微图案技术,组织工程”。

结果与结论:通过微图案技术可形成图案化的细胞排列,进而控制干细胞的形状,调控干细胞融合和分化等,以形成可用于组织替代物的人工组织工程产品,被广泛应用于骨组织工程、肌肉组织工程、血管组织工程及神经组织工程及肝脏组织工程研究中。然而,利用微图案技术构建人工组织的过程中,仍有许多细胞生物学机制和内在机制亟待进一步探索和阐明,例如:如何通过微图案技术构建人工肌肉组织,如何纯化许旺细胞,以及进一步促进微图案技术在血管组织工程和肝脏组织工程中的发展和创新等问题。

Abstract:

 BACKGROUND: With the constant innovation and development of micro-pattern technology, it has also been applied widely in cell biology, tissue engineering and regenerative medicine, which provides new impetus for the construction of artificial tissues in vitro.

OBJECTIVE: To summarize the classification, characteristics and application of micro-pattern technique in tissue engineering.
METHODS: The authors performed a data retrieval of PubMed, Web of Science and CNKI to search the articles addressing micro-pattern technique and its application in tissue engineering published from 2001 to 2017, and reviewed the literatures systematically. The keywords were “micro-pattern technique, tissue engineering” in English and Chinese, respectively.

RESULTS AND CONCLUSION: Using the micro-pattern technique, patterned cell alignment is formed to control the shape of stem cells, and regulate stem cell fusion and differentiation. Moreover, artificial tissue engineering products have been developed and used as tissue substitutes for bone tissue engineering, muscle tissue engineering, vascular tissue engineering, nerve tissue engineering and liver tissue engineering. However, cell biology mechanisms and internal mechanisms underlying the use of micro-pattern technique in the artificial tissue construction need to be further explored and elucidated. For example, future investigations are warranted on how to construct artificial muscle tissue using the micro-pattern technique, how to purify Schwann cells, as well as the development and innovation of micro-pattern technique in vascular and liver tissue engineering research.
