Bridging Wright-Fisher and Moran models

Arthur Alexandre, Alia Abbara, Cecilia Fruet, Claude Loverdo, Anne-Florence Bitbol

The Wright-Fisher model and the Moran model are both widely used in population genetics. They describe the time evolution of the frequency of an allele in a well-mixed population with fixed size. We propose a simple and tractable model which bridges the Wright-Fisher and the Moran descriptions. We…

Rigidity percolation and active advection synergize in the actomyosin cortex to drive amoeboid cell motility

Juan Manuel García-Arcos, Johannes Ziegler, Silvia Grigolon, Loïc Reymond, Gaurav Shajepal, Cédric Cattin, Alexis Lomakin, Daniel Müller, Verena Ruprecht, Stefan Wieser, Raphael Voituriez, Matthieu Piel

• Actin filament density at the cell front controls bleb protrusion • A solid-like actomyosin cortex in the cell middle sterically enables cell propulsion • The material properties of amoeboid cells organize spatially by advected percolation • Stable blebs in adhesive environments can fragment into…
