In the world of clinic treatments, 3D-printed tissue constructs have emerged as a less invasive treatment method for various ailments. Printing processes, scaffold and scaffold free materials, cells used, and imaging for analysis are all factors that must be observed in order to develop successful 3D tissue constructs for clinical applications. However, current research in 3D bioprinting model development lacks diverse methods of successful vascularization as a result of issues with scaling, size, and variations in printing method. This study analyzes the methods of printing, bioinks used, and analysis techniques in 3D bioprinting for vascularization. These methods are discussed and evaluated to determine the most optimal strategies of 3D bioprinting for successful vascularization. Integrating stem and endothelial cells in prints, selecting the type of bioink according to its physical properties, and choosing a printing method according to physical properties of the desired printed tissue are steps that will aid in the successful development of a bioprinted tissue and its vascularization.
在临床治疗领域,3D打印组织构建体已成为一种针对各种疾病的侵入性较小的治疗方法。为了开发出适用于临床应用的成功的3D组织构建体,打印过程、支架及无支架材料、所用细胞以及用于分析的成像都是必须考虑的因素。然而,由于缩放、尺寸和打印方法的差异等问题,目前3D生物打印模型开发方面的研究缺乏多种成功实现血管化的方法。本研究分析了用于血管化的3D生物打印中的打印方法、所用生物墨水和分析技术。对这些方法进行了讨论和评估,以确定3D生物打印实现成功血管化的最优化策略。在打印物中整合干细胞和内皮细胞、根据生物墨水的物理特性选择其类型以及根据所需打印组织的物理特性选择打印方法,这些步骤将有助于生物打印组织及其血管化的成功开发。
