A theory for coexistence and selection of branched actin networks in a shared and finite pool of monomers
Valentin Wössner, Falko Ziebert, Ulrich S. Schwarz
Cellular actin structures are continuously turned over while keeping similar sizes. Since they all compete for a shared pool of actin monomers, the question arises how they can coe…
Active gel theory for cell migration with two myosin isoforms
Nils O. Winkler, Oliver M. Drozdowski, Falko Ziebert +1
Myosin II molecular motors slide actin filaments relatively to each other and are essential for force generation, motility and mechanosensing in animal cells. For non-muscle cells,…
Three-dimensional chiral active Ornstein-Uhlenbeck model for helical motion of microorganisms
Leon Lettermann, Falko Ziebert, Mirko Singer +2
Active movement is essential for the survival of microorganisms like bacteria, algae and unicellular parasites. In three dimensions, both swimming and gliding microorganisms often…
The positioning of stress fibers in contractile cells minimizes internal mechanical stress
Lukas Riedel, Valentin Wössner, Dominic Kempf +3
The mechanics of animal cells is strongly determined by stress fibers, which are contractile filament bundles that form dynamically in response to extracellular cues. Stress fibers…
Active gel model for one-dimensional cell migration coupling actin flow and adhesion dynamics
Valentin Wössner, Oliver M. Drozdowski, Falko Ziebert +1
Migration of animal cells is based on the interplay between actin polymerization at the front, adhesion along the cell-substrate interface, and actomyosin contractility at the back…
Physical phase field model for phagocytosis
Benjamin Winkler, Mohammad Abu Hamed, Alexander A. Nepomnyashchy +1
We propose and study a simple, physical model for phagocytosis, i.e. the active, actin-mediated uptake of micron-sized particles by biological cells. The cell is described by the p…
