Tissue engineering strives to create neotissues capable of restoring function. Scaffold-free technologies have emerged that can recapitulate native tissue function without the use of an exogenous scaffold. This review will survey, in particular, the self-assembling and self-organization processes as scaffold-free techniques. Characteristics and benefits of each process are described, and key examples of tissues created using these scaffold-free processes are examined to provide guidance for future tissue-engineering developments. We aim to explore the potential of self-assembly and self-organization scaffold-free approaches, detailing the recent progress in the in vitro tissue engineering of biomimetic tissues with these methods toward generating functional tissue replacements.
组织工程致力于创造能够恢复功能的新组织。已经出现了无支架技术,可以在不使用外源性支架的情况下再现天然组织的功能。本综述特别调查了无支架技术中的自组装和自组织过程。描述了每个过程的特点和优点,并检查了使用这些无支架过程创建的组织的关键示例,为未来的组织工程发展提供指导。我们旨在探讨自组装和自组织无支架方法的潜力,详细介绍最近使用这些方法在体外仿生组织工程中构建功能性组织替代物的进展。
