摘要:


文题释义:

3D生物打印:是一套可用于制造包含细胞以及材料的三维物理结构的新技术,其可以定义为操纵含有细胞的生物墨水来制造生命结构的过程。该技术通过使用计算机来构筑三维模型,再配置特制的生物墨水,经3D生物打印机构建出复杂的功能活组织或人造器官。目前3D打印医学模型的运用已十分广泛,但在人体器官组织的制备上仍处于研究阶段。
生物墨水:是3D生物打印技术的核心,也是3D生物打印中制备人体组织细胞所负载支架的主要挑战之一,指将成千上万个由天然的或人工合成的生物材料、生物活性分子、细胞等混合物放置于3D打印机的墨盒中进行生物打印的材料。常见的生物墨水有天然材料、合成材料。


背景:通过选用合适的生物墨水,3D打印技术可用以制造人体组织和器官的代替物,并在人体内发挥作用。近些年来3D打印技术发展迅速,在再生医学中有着巨大的应用潜力。

目的:介绍3D打印用生物墨水的类型,并综述生物墨水的分类、应用、优缺点及未来愿景。
方法:以“3D printing,Biological ink,Tissue engineering,hydrogel,Synthetic material,Cytoactive factor,3D打印、生物墨水、组织工程”为检索词,运用计算机检索2000-2022年以来发表在PubMed、CNKI数据库中的相关文献,最终纳入83篇进行综述。

结果与结论:在过去的几十年里,生物3D打印技术发展迅速,在组织工程和生物医学等各个领域都受到了极大的关注。相对于传统生物支架制造方法在功能性及结构方面受到的限制,3D打印可以更好地模拟生物组织复杂的结构,并且具有合适的力学、流变学和生物学特性。生物墨水是3D打印中必不可少的一部分,通过生物材料制备的生物墨水,经打印后产生的生物支架在组织修复和再生医学等方面有着巨大的科研潜力及临床意义,其材料的研究本身也越来越受到专家们的重视。3D打印生物墨水的材料各种各样,有天然材料也有合成材料,还有一些不需要任何额外生物材料的细胞聚集体,并且各种材料在实际运用中的功效各不相同。未来会有越来越多的生物墨水被研制用于组织工程,需要通过充足的实验模拟及设备测试来对生物墨水的可打印性进行分析,从而满足实际的医用需求。

Abstract: BACKGROUND: With the right bio-inks, 3D printing can be used to create replacements for human tissues and organs that work inside the body. In recent years, 3D printing technology has developed rapidly and has great application potential in regenerative medicine.
OBJECTIVE: To introduce the types of bio-inks for 3D printing, and review the classification, application, advantages and disadvantages of bio-inks, as well as the future vision.
METHODS: With “3D printing, biological ink, tissue engineering, hydrogel, synthetic material, cytoactive factor” as search terms, relevant articles published on PubMed and CNKI databases from 2000 to 2022 were searched by computer and finally 83 articles were included for review. 
RESULTS AND CONCLUSION: 3D bioprinting technology has developed rapidly over the past few decades and has received great attention in various fields, including tissue engineering and biomedicine. Compared with the limitations of traditional biological scaffold manufacturing methods in terms of function and structure, 3D printing can better simulate the complex structure of biological tissues and has appropriate mechanical, rheological and biological characteristics. Bio-ink is an essential part of 3D printing. Bioscaffolds produced by printing bio-ink prepared by biological materials have great scientific potential and clinical significance in tissue repair and regenerative medicine. The research of the materials itself is also getting more and more attention from experts. Bio-inks for 3D printing come in a variety of materials, from natural to synthetic, to aggregations of cells that do not require any additional biomaterials, and their usefulness in practical use varies. In the future, more and more bio-inks will be developed for tissue engineering. It is necessary to analyze the printability of bio-inks through sufficient experimental simulation and equipment testing to meet the actual medical needs.
