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…
Fractional viscoelastic models for power-law materials
Alessandra Bonfanti, Jonathan Louis Kaplan, Guillaume Charras +1
Soft materials often exhibit a distinctive power-law viscoelastic response arising from broad distribution of time-scales present in their complex internal structure. A promising t…
A tug-of-war between stretching and bending in living cell sheets
Pierre Recho, Jonathan Fouchard, Tom Wyatt +3
The balance between stretching and bending deformations characterizes shape transitions of thin elastic sheets. While stretching dominates the mechanical response in tension, bendi…
Single-cell approaches to cell competition: high-throughput imaging, machine learning and simulations
Daniel Gradeci, Anna Bove, Guillaume Charras +2
Cell competition is a quality control mechanism in tissues that results in the elimination of less fit cells. Over the past decade, the phenomenon of cell competition has been iden…
