Abstract

Currently, the fabrication of a functional vascular network to maintain the viability of engineered tissues is a major bottleneck in the way of developing a more advanced engineered construct. Inspired by vasculogenesis during the embryonic period, the prevascularization strategies have focused on optimizing communications and interactions of cells, biomaterial and culture conditions to develop a capillary-like network to tackle the aforementioned issue. Many of these studies employ a combination of endothelial lineage cells and supporting cells such as mesenchymal stem cells, fibroblasts, and perivascular cells to create a lumenized endothelial network. These supporting cells are necessary for the stabilization of the newly developed endothelial network. Moreover, to optimize endothelial network development without impairing biomechanical properties of scaffolds or differentiation of target tissue cells, several other factors, including target tissue, endothelial cell origins, the choice of supporting cell, culture condition, incorporated pro-angiogenic factors, and choice of biomaterial must be taken into account. The prevascularization method can also influence the endothelial lineage cell/supporting cell co-culture system to vascularize the bioengineered constructs. This review aims to investigate the recent advances on standard cells used in in vitro prevascularization methods, their co-culture systems, and conditions in which they form an organized and functional vascular network.

摘要

目前,构建功能性血管网络以维持工程组织的活力是开发更先进工程构建体的主要瓶颈。受胚胎期血管生成的启发,预血管化策略专注于优化细胞、生物材料和培养条件之间的通讯与相互作用,以形成类似毛细血管的网络来解决上述问题。许多此类研究采用内皮谱系细胞与间充质干细胞、成纤维细胞和周血管细胞等支持细胞相结合的方式,构建有腔内皮网络。这些支持细胞对于新形成的内皮网络的稳定至关重要。此外,为了在不损害支架生物力学性能或靶组织细胞分化的情况下优化内皮网络发育,还必须考虑其他几个因素,包括靶组织、内皮细胞来源、支持细胞的选择、培养条件、添加的促血管生成因子以及生物材料的选择。预血管化方法也会影响内皮谱系细胞/支持细胞共培养系统,从而使生物工程构建体血管化。本综述旨在探讨体外预血管化方法中使用的标准细胞、它们的共培养系统以及形成有组织和功能性血管网络的条件的最新进展。
