Optogenetic generation of leader cells reveals a force-velocity relation for collective cell migration

L. Rossetti, S. Grosser, J. F. Abenza, L. Valon, P. Roca-Cusachs, R. Alert, X. Trepat

The paper uses optogenetic Rac1 activation to generate leader cells and shows that collective cell migration requires global mechanical organization rather than autonomous leader action.

Capillary interactions drive the self-organization of bacterial colonies

M. W. Black, C. Fei, R. Alert, N. S. Wingreen, J. W. Shaevitz

This study shows capillary forces organize bacterial colonies into dense, nematic groups and influence their collective dynamics.

Frictiotaxis underlies adhesion-independent durotaxis

A. Shellard, K. W. Weissenbruch, P. Hampshire, N. Stillman, C. Dix, R. Thorogate, A. Imbert, G. Charras, R. Alert, R. Mayor

The paper shows cells can migrate towards stiffer substrates without strong adhesions, proposing a new mechanism called frictiotaxis based on friction gradients.

Stiffness-dependent active wetting enables optimal collective cell durotaxis

M. E. Pallares, I. Pi-Jauma, I. C. Fortunato, V. Grazu, M. Gomez-Gonzalez, P. Roca-Cusachs, J. M. de la Fuente, R. Alert, R. Sunyer, J. Casademunt, X. Trepat

This study shows that cellular clusters migrate optimally on stiffness gradients by balancing active traction, contractility, and surface tension, based on their wetting properties.

Self-assembly of tessellated tissue sheets by growth and collision

M. A. Heinrich, R. Alert, A. E. Wolf, A. Kosmrlj, D. J. Cohen

This study investigates tissue-tissue interactions through collisions and develops a design tool for self-assembling complex tessellations.

Morphogenesis and cell ordering in confined bacterial biofilms

Q. Zhang, J. Li, J. Nijjer, H. Lu, M. Kothari, R. Alert, T. Cohen, J. Yan

This study investigates how confined environments influence biofilm morphology and cell ordering in Vibrio cholerae using single-cell imaging and biomechanical analysis.

Size-dependent patterns of cell proliferation and migration in freely-expanding epithelia

M. A. Heinrich, R. Alert, J. LaChance, T. J. Zajdel, A. Kosmrlj, D. J. Cohen

This study shows that expanding epithelial monolayers exhibit size-dependent patterns of proliferation and migration, with memory effects based on initial tissue size rather than current conditions.
