In this paper, a macroscopic model describing endothelial cell migration on bioactive micropatterned polymers is presented. It is based on a system of partial differential equations of Patlak-Keller-Segel type that describes the evolution of the cell densities. The model is studied mathematically and numerically. We prove existence and uniqueness results of the solution to the differential system. We also show that fundamental physical properties such as mass conservation, positivity and boundedness of the solution are satisfied. The numerical study allows us to show that the modeling results are in good agreement with the experiments.
本文提出了一个描述生物活性微图案聚合物上内皮细胞迁移的宏观模型。它基于一个 Patlak-Keller-Segel 型偏微分方程组系统,描述了细胞密度的演化。该模型进行了数学和数值研究。我们证明了微分系统解的存在唯一性结果。我们还表明,该解满足质量守恒、正定性和有界性等基本物理性质。数值研究表明,模型结果与实验结果吻合良好。
