Chemotaxis and Haptotaxis on Cellular Level
  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.
