Cell divisions suppress dynamical correlations in solid tissues
Ali Tahaei, Ahandeep Manna, Marko Popović
Developing tissues often maintain mechanical coherence while continuously remodeling through cellular processes such as cell divisions and rearrangements. In this way, they are an…
Random traction yielding transition in epithelial tissues
Aboutaleb Amiri, Charlie Duclut, Frank Jülicher +1
We investigate how randomly oriented cell traction forces lead to fluidisation in a vertex model of epithelial tissues. We find that the fluidisation occurs at a critical value of…
Scaling description of creep flow in amorphous solids
Marko Popović, Tom W. J. de Geus, Wencheng Ji +2
Amorphous solids such as coffee foam, toothpaste or mayonnaise display a transient creep flow when a stress is suddenly imposed. The associated strain rate is commonly found to…
Elasto-plastic description of brittle failure in amorphous materials
Marko Popović, Tom W. J. de Geus, Matthieu Wyart
The response of amorphous materials to an applied strain can be continuous, or instead display a macroscopic stress drop when a shear band nucleates. Such discontinuous response ca…
Triangles bridge the scales: Quantifying cellular contributions to tissue deformation
Matthias Merkel, Raphaël Etournay, Marko Popović +3
In this article, we propose a general framework to study the dynamics and topology of cellular networks that capture the geometry of cell packings in two-dimensional tissues. Such…
Active dynamics of tissue shear flow
Marko Popović, Amitabha Nandi, Matthias Merkel +4
We present a hydrodynamic theory to describe shear flows in developing epithelial tissues. We introduce hydrodynamic fields corresponding to state properties of constituent cells a…
