Curvature induces active velocity waves in rotating multicellular spheroids
Tom Brandstätter, David B. Brückner, Yu Long Han +3
The multicellular organization of diverse systems, such as embryos, intestines and tumours, relies on the coordinated migration of cells in 3D curved environments. In these setting…
Collective durotaxis of cohesive cell clusters on a stiffness gradient
Irina Pi-Jaumà, Ricard Alert, Jaume Casademunt
Many types of motile cells perform durotaxis, namely, directed migration following gradients of substrate stiffness. Recent experiments have revealed that cell monolayers can migra…
Cellular Sensing Governs the Stability of Chemotactic Fronts
Ricard Alert, Alejandro Martínez-Calvo, Sujit S. Datta
In contexts ranging from embryonic development to bacterial ecology, cell populations migrate chemotactically along self-generated chemical gradients, often forming a propagating f…
Living cells on the move
Ricard Alert, Xavier Trepat
Spectacular collective phenomena such as jamming, turbulence, wetting, and waves emerge when living cells migrate in groups.
Active Turbulence
Ricard Alert, Jaume Casademunt, Jean-François Joanny
Active fluids exhibit spontaneous flows with complex spatiotemporal structure, which have been observed in bacterial suspensions, sperm cells, cytoskeletal suspensions, self-propel…
Scaling regimes of active turbulence with external dissipation
Berta Martínez-Prat, Ricard Alert, Fanlong Meng +5
Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experime…
Chemotactic smoothing of collective migration
Tapomoy Bhattacharjee, Daniel B. Amchin, Ricard Alert +2
Collective migration -- the directed, coordinated motion of many self-propelled agents -- is a fascinating emergent behavior exhibited by active matter that has key functional impl…
