三维(3D)生物打印在制造仿生人体组织和复杂移植材料方面表现出了巨大的潜力。该技术利用由放置在生物材料内的细胞元素组成的生物墨水。间充质基质细胞 (MSC) 是 3D 生物打印中细胞选择的一个有吸引力的选择。间充质干细胞可以从多种组织中分离出来,具有巨大的增殖能力,并且可以分化为多种定型细胞类型。尽管间充质干细胞具有前景广阔的特性,但其使用也存在一些缺点。这些担忧与整个 3D 生物打印过程中的离体操作有关。本文的手稿旨在提供有关这些事件的当前证据,并提出在医学领域广泛扩展 3D 生物打印后最大限度降低患者风险的方法。
Three-dimensional (3D) bioprinting has demonstrated great potential for the fabrication of biomimetic human tissues and complex graft materials. This technology utilizes bioinks composed of cellular elements placed within a biomaterial. Mesenchymal stromal cells (MSCs) are an attractive option for cell selection in 3D bioprinting. MSCs can be isolated from a variety of tissues, can pose vast proliferative capacity and can differentiate to multiple committed cell types. Despite their promising properties, the use of MSCs has been associated with several drawbacks. These concerns are related to the ex vivo manipulation throughout the process of 3D bioprinting. The herein manuscript aims to present the current evidence surrounding these events and propose ways to minimize the risks to the patients following widespread expansion of 3D bioprinting in the medical field.
