摘要:

背景:近年来,研究者将最先应用于工程领域的3D打印技术嫁接到组织工程学中,希冀利用3D生物打印技术进行体外组织、器官复制过程,并取得了一些令人惊喜的成果。
目的:从3D打印技术的原理、打印操作步骤、与组织工程学的关系、优势和难题、临床应用等方面对其目前的发展趋势做一概述。
方法:第一作者应用计算机检索2000年1月至2013年10月PubMed数据库、中国期刊全文数据库、维普中文期刊网有关3D生物打印技术在组织工程中应用的文章,英文检索词“three-dimensional bioprinting, tissue engineering, rapid prototyping technology, scaffold materials, selective laser sintering, fused deposition modeling, stereolithography ”,中文检索词“3D生物打印,组织工程学,快速成型技术,支架材料,选择性激光烧结,熔融沉积成型,立体光刻技术”,排除重复性研究。共检索到79篇相关文献,其中52篇文献符合纳入标准。
结果与结论:3D生物打印就是借助影像技术(CT、MRI)资料的辅助,应用计算机辅助设计技术虚拟出待构建体的三维结构,然后利用相应的材料,逐层创建出实体的一种组织工程学技术。其具有高精度、构建速度快,可实现按需制造等优势,但也面对力学、生物学等方面的难题,临床应用前景广阔。

Abstract:

BACKGROUND: Three-dimensional bioprinting technology is the emerging technology in recent years, which is one of the branches of tissue engineering. The three-dimensional bioprinting technology has been used in the reproduction process of in vitro tissues and organs, which has achieved surprising outcomes.
OBJECTIVE: To review the three-dimensional bioprinting technology in terms of its principles, operating steps, relationships with tissue engineering, advantages and challenges, as well as clinical applications.
METHODS: The first author did a computer-aided retrieval of the PubMed database, CNKI database, and CQVIP database for articles relevant to three-dimensional bioprinting technology used in tissue engineering published between January 2000 and October 2000. The key words were “three-dimensional bioprinting, tissue engineering, rapid prototyping technology, scaffold materials, selective laser sintering, fuseddeposition modeling, stereolithography” in English and Chinese. Repetitive studies were excluded, and 52 of 79 related literatures were adopted in result analysis.
RESULTS AND CONCLUSION: Three-dimensional bioprinting technology is one of the branches of tissue engineering, which can build a virtual three-dimensional structure layer by layer under the computer-aided design technology, with the help of imaging data information (including CT and MRI). This technology has the advantages of high precision, high building speed, fabrication on demand, and also has the challenges in engineering mechanics and biological activities. In a word, it is a meaningful and promising technology in clinical application.
