2.方法使用单独的实验来研究这些问题可能是昂贵且耗时的,这就是为什么我们在这里提出一个数学框架来探索不同种子细胞分布对氧浓度、细胞密度、VEGF 梯度和血管网络形成的影响。该框架包含一个细胞溶质模型,根据体外数据进行参数化,量化一系列环境氧气条件下的细胞密度、摄氧量和 VEGF 释放(Coy 等人,引文 2020),并覆盖内皮芽生长、血流和血管内氧气输送的离散模型。该框架将 EngNT 视为一个由细胞接种的水凝胶组成的圆柱体,周围环绕着不可渗透的材料鞘,因此与外部组织的分子交换和 EC 入侵仅发生在近端和远端残端。
2. MethodsInvestigating such questions using experiments in isolation can be costly and time consuming that is why we propose here a mathematical framework to explore the impact of different seeded cell distributions upon oxygen concentration, cell densities, VEGF gradients and vascular network formation. This framework comprises a cell-solute model, parameterised against in vitro data, which quantify cell density, oxygen uptake and VEGF release at a range of ambient oxygen conditions (Coy et al. Citation 2020), overlaid with a discrete model for endothelial sprout growth, blood flow and intravascular transport of oxygen. This framework considers the EngNT as a cylinder of cell-seeded hydrogel surrounded by an impermeable sheath of material, so that molecular exchanges with the outside tissue and EC invasion only happen at the proximal and distal stumps.
