Programming filamentous network mechanics by compression
Bart E. Vos, Luka C. Liebrand, Mahsa Vahabi +6
Fibrous networks are ideal functional materials since they provide mechanical rigidity at low weight. Such structures are omnipresent in natural biomaterials from cells to tissues,…
Force percolation of contractile active gels
José Alvarado, Misha Sheinman, Abhinav Sharma +2
Cells and tissues exert forces and can actively change shape. This strikingly autonomous behavior is powered by the cytoskeleton, which includes an active gel of actin filaments, c…
Reply to Comment on "Anomalous Discontinuity at the Percolation Critical Point of Active Gels"
M. Sheinman, A. Sharma, F. C. MacKintosh
In this reply we discuss definition and estimation of the Fisher exponent in the no-enclaves percolation (NEP) model.
Self-organization of stress patterns drives state transitions in actin cortices
Tzer Han Tan, Maya Malik Garbi, Enas Abu-Shah +6
Biological functions rely on ordered structures and intricately controlled collective dynamics. In contrast to systems in thermodynamic equilibrium, order is typically established…
Broken Detailed Balance of Filament Dynamics in Active Networks
J. Gladrow, N. Fakhri, F. C. MacKintosh +2
Myosin motor proteins drive vigorous steady-state fluctuations in the actin cytoskeleton of cells. Endogenous embedded semiflexible filaments such as microtubules, or added filamen…
