摘要：
细胞在导航其自然环境时会遇到多样化的物理和化学信号。然而，它们对同时存在多种信号的响应仍不明确。特别是，地形与趋化梯度对细胞迁移行为的影响尚不充分研究。在本文中，我们研究了趋化过程中地形障碍的影响。我们的方法涉及修改Keller-Segel模型，引入一个空间依赖的趋化系数。通过我们的分析，我们证明该系数在防止细胞浓度爆发现象中起关键作用。
英文摘要：
Cells encounter a diverse array of physical and chemical signals as they navigate their natural surroundings. However, their response to the simultaneous presence of multiple cues remains elusive. Particularly, the impact of topography alongside a chemotactic gradient on cell migratory behavior remains insufficiently explored. In this paper, we investigate the effects of topographical obstacles during chemotaxis. Our approach involves modifying the Keller-Segel model, incorporating a spatially dependent coefficient of chemotaxis. Through our analysis, we demonstrate that this coefficient plays a crucial role in preventing blow-up phenomena in cell concentration.
