Chemotaxis and Haptotaxis on Cellular Level

TL;DR

This paper investigates how chemotaxis and haptotaxis influence the shape and movement of fast migrating cells, revealing similarities in their migration patterns despite biological differences.

Contribution

It provides a comparative analysis of chemotaxis and haptotaxis effects on cell motility and shape, highlighting their similar outcomes after initial adaptation.

Findings

Cells stabilize shape after initial adjustment

Migration resembles advection post-stabilization

Chemotaxis and haptotaxis produce similar migration patterns

Abstract

Chemotaxis and haptotaxis have been a main theme in the macroscopic study of bacterial and cellular motility. In this work we investigate the influence these processes have on the shape and motility of fast migrating cells. We note that despite their biological and modelling differences, the cells exhibit many similarities in their migration. We moreover see, that after an initial adjustment phase, the cells obtain a stable shape and their motion is similar to advection.
