Mechanics of the cellular actin cortex: from signalling to shape change
Manasi Kelkar, Pierre Bohec, Guillaume Charras
The actin cortex is a thin layer of actin, myosin, and actin binding proteins that underlies the membrane of most animal cells. It is highly dynamic and can undergo remodelling on…

Distribution of active forces in the cell cortex
P. Bohec, J. Tailleur, F. van Wijland +2
In this work, we study in detail the distribution of stochastic forces generated by the molecular motors activity, in the actin cortex of pre-muscular cells. By combining active an…

Power Spectrum of Out-of-equilibrium Forces in Living Cells : Amplitude and Frequency Dependence
Francois Gallet, Delphine Arcizet, Pierre Bohec +1
Living cells exhibit an important out-of-equilibrium mechanical activity, mainly due to the forces generated by molecular motors. These motor proteins, acting individually or colle…
