mechanisms. Here we review recently developed tools to quantify the forces generated by …

Collective cell migration: a physics perspective

V Hakim, P Silberzan - Reports on Progress in Physics, 2017‏ - iopscience.iop.org
Cells have traditionally been viewed either as independently moving entities or as
somewhat static parts of tissues. However, it is now clear that in many cases, multiple cells …

confluent epithelial tissues consisting of tens of thousands of cells, with a level of detail …

Physical models of collective cell motility: from cell to tissue

BA Camley, WJ Rappel - Journal of physics D: Applied physics, 2017‏ - iopscience.iop.org
In this article, we review physics-based models of collective cell motility. We discuss a range
of techniques at different scales, ranging from models that represent cells as simple self …

Cellular contraction and polarization drive collective cellular motion

J Notbohm, S Banerjee, KJC Utuje, B Gweon, H Jang… - Biophysical journal, 2016‏ - cell.com
Coordinated motions of close-packed multicellular systems typically generate cooperative
packs, swirls, and clusters. These cooperative motions are driven by active cellular forces …

Contact inhibition of locomotion determines cell–cell and cell–substrate forces in tissues

J Zimmermann, BA Camley, WJ Rappel… - Proceedings of the …, 2016‏ - pnas.org
Cells organized in tissues exert forces on their neighbors and their environment. Those
cellular forces determine tissue homeostasis as well as reorganization during embryonic …

Emergent collective chemotaxis without single-cell gradient sensing

B Camley, J Zimmermann, H Levine, WJ Rappel - Biophysical Journal, 2016‏ - cell.com
Many eukaryotic cells chemotax, sensing and following chemical gradients. However,
experiments have shown that even under conditions when single cells do not chemotax …

Inference of internal stress in a cell monolayer

V Nier, S Jain, CT Lim, S Ishihara, B Ladoux, P Marcq - Biophysical journal, 2016‏ - cell.com
We combine traction force data with Bayesian inversion to obtain an absolute estimate of the
internal stress field of a cell monolayer. The method, Bayesian inversion stress microscopy …
