Bistability of cellular traction on strain-stiffening substrates
Irina Pi-JaumÃ, Jaume Casademunt, Ricard Alert
To migrate, cells exert traction forces on the extracellular matrix (ECM) -- a biopolymer network that often exhibits nonlinear strain-stiffening elasticity. Cellular tractions can…

Dynamical arrest in active nematic turbulence
Ido Lavi, Ricard Alert, Jean-François Joanny +1
Active fluids display spontaneous turbulent-like flows known as active turbulence. Recent work revealed that these flows have universal features, independent of the material proper…

Cell clusters sense their global shape to drive collective migration
Joan Térmens, Irina Pi-JaumÃ, Ido Lavi +4
The collective migration of epithelial groups of cells plays a central role in processes such as embryo development, wound healing, and cancer invasion. While finite cell clusters…
