Stress percolation criticality of glass to fluid transition in active cell layers
Siavash Monfared, Guruswami Ravichandran, Jose E. Andrade +1
Using three-dimensional representation of confluent cell layers, we map the amorphous solid to fluid phase transition in active cell layers onto the two-dimensional (2D) site perco…
Collective rotational motion of freely-expanding T84 epithelial cell colonies
Flora Ascione, Sergio Caserta, Speranza Esposito +6
Coordinated rotational motion is an intriguing, yet still elusive mode of collective cell migration, which is relevant in pathological and morphogenetic processes. Most of the stud…
Differential elasticity in lineage segregation of embryonic stem cells
Christine M. Ritter, Natascha Leijnse, Younes Farhangi Barooji +3
The question of what guides lineage segregation is central to development, where cellular differentiation leads to segregated cell populations destined for specialized functions. H…
Symmetry-restoring crossover from defect-free to defect-laden turbulence in polar active matter
Benjamin H. Andersen, Julian Renaud, Jonas Rønning +2
Coherent flows of self-propelled particles are characterized by vortices and jets that sustain chaotic flows, referred to as active turbulence. Here, we reveal a crossover between…
Nematic order condensation and topological defects in inertial active nematics
Roozbeh Saghatchi, Mehmet Yildiz, Amin Doostmohammadi
Living materials at different length scales manifest active nematic features such as orientational order, nematic topological defects, and active nematic turbulence. Using numerica…
Self-sustained oscillations of active viscoelastic matter
Emmanuel L. C. VI M. Plan, Huong Le Thi, Julia M. Yeomans +1
Models of active nematics in biological systems normally require complexity arising from the hydrodynamics involved at the microscopic level as well as the viscoelastic nature of t…
Distinct impacts of polar and nematic self-propulsion on active unjamming
Varun Venkatesh, Chandana Mondal, Amin Doostmohammadi
Though jamming transitions are long studied in condensed matter physics and granular systems, much less is known about active jamming (or unjamming), which commonly takes place in…
Bridging microscopic cell dynamics to nematohydrodynamics of cell monolayers
Aleksandra Ardaševa, Romain Mueller, Amin Doostmohammadi
It is increasingly being realized that liquid-crystalline features can play an important role in the properties and dynamics of cell monolayers. Here, we present a cell-based model…
Fluctuation-induced dynamics of nematic topological defects
Lasse Bonn, Aleksandra Ardaseva, Romain Mueller +2
Topological defects are increasingly being identified in various biological systems, where their characteristic flow fields and stress patterns are associated with continuous activ…
