Actin Flows Mediate a Universal Coupling between Cell Speed and Cell Persistence
Paolo Maiuri,Jean-François Rupprecht,Stefan Wieser,Verena Ruprecht,Olivier Bénichou,Nicolas Carpi,Mathieu Coppey,Simon de Beco,Nir S. Gov,Carl-Philipp Heisenberg,Carolina Lage Crespo,Franziska Lautenschlaeger,Maël Le Berre,Ana-Maria Lennon-Duménil,Matthew Raab,Hawa Racine Thiam,Matthieu Piel,Michael Sixt,Raphaël Voituriez +18 more
TL;DR: It is shown on the basis of experimental data in vitro and in vivo that cell persistence, which quantifies the straightness of trajectories, is robustly coupled to cell migration speed, and suggested that this universal coupling constitutes a generic law of cell migration.
Journal ArticleDOI
Exit Time Distribution in Spherically Symmetric Two-Dimensional Domains
TL;DR: In this article, the authors proposed both an exact solution relying on a matrix inversion, and an approximate explicit solution for an exit of vanishing size and to be accurate even for large exits.
Journal ArticleDOI
The escape problem for mortal walkers.
TL;DR: The escape problem for random walkers that may eventually die, decay, bleach, or lose activity during their diffusion towards an escape or reactive region on the boundary of a confining domain is introduced and three asymptotic regimes of small, intermediate, and large death rates are revealed.
Journal ArticleDOI
Shaping the zebrafish myotome by intertissue friction and active stress
Sham Tlili,Jianmin Yin,Jean-François Rupprecht,Mario A. Mendieta-Serrano,G. Weissbart,N. Verma,Xiang Teng,Yusuke Toyama,Jacques Prost,Jacques Prost,Timothy E. Saunders,Timothy E. Saunders +11 more
TL;DR: This work reveals how spatially modulating the mechanical environment around and within tissues can lead to complex organ shape formation and sheds light on how a spatiotemporal sequence of local cellular events can have a nonlocal and irreversible mechanical impact at the tissue scale, leading to robust organ shaping.
Journal ArticleDOI
Kinetics of Active Surface-Mediated Diffusion in Spherically Symmetric Domains
TL;DR: In this paper, an exact calculation of the mean first-passage time to a target on the surface of a 2D or 3D spherical domain, for a molecule alternating phases of surface diffusion on the domain boundary and phases of bulk diffusion, is presented.
