WebAug 23, 2024 · In this article, we present a mathematical model of amoeboid motility that combines noisy bistable kinetics with a dynamic phase field for the cell shape. To capture cell-to-cell variability, we introduce a single parameter for tuning the balance between polarity formation and intracellular noise. WebSep 21, 2024 · In the first frame, all flagella rotate counterclockwise (CCW), which promotes the bundling of all filaments behind the cell and results in straight swimming. In the second frame, one motor has...
