Velocity fields in a collectively migrating epithelium.
Petitjean L, Reffay M, Grasland-Mongrain E, Poujade M, Ladoux B, Buguin A, Silberzan P. Petitjean L, et al. Biophys J. 2010 May 19;98(9):1790-800. doi: 10.1016/j.bpj.2010.01.030. Biophys J. 2010. PMID: 20441742 Free PMC article.
We report quantitative measurements of the velocity field of collectively migrating cells in a motile epithelium. The migration is triggered by presenting free surface to an initially confluent monolayer by using a microstencil technique that does not damage the cel …

Collective migration of an epithelial monolayer in response to a model wound.
Poujade M, Grasland-Mongrain E, Hertzog A, Jouanneau J, Chavrier P, Ladoux B, Buguin A, Silberzan P. Poujade M, et al. Proc Natl Acad Sci U S A. 2007 Oct 9;104(41):15988-93. doi: 10.1073/pnas.0705062104. Epub 2007 Sep 28. Proc Natl Acad Sci U S A. 2007. PMID: 17905871 Free PMC article.
On the other hand, we have identified very active "leader cells" that precede a small cohort and destabilize the border by a fingering instability. The sides of the fingers reveal a pluricellular actin "belt" that may be at the origin of a mechanical s …

Directional persistence of chemotactic bacteria in a traveling concentration wave.
Saragosti J, Calvez V, Bournaveas N, Perthame B, Buguin A, Silberzan P. Saragosti J, et al. Among authors: buguin a. Proc Natl Acad Sci U S A. 2011 Sep 27;108(39):16235-40. doi: 10.1073/pnas.1101996108. Epub 2011 Sep 14. Proc Natl Acad Sci U S A. 2011. PMID: 21918111 Free PMC article.
[Collective cell migration: a fair sharing between leader cells and supracellular coordination].

Med Sci (Paris). 2014 Aug-Sep;30(8-9):736-8. doi: 10.1051/medsci/20143008007. Epub 2014 Sep 1. Med Sci (Paris). 2014. PMID: 25174746 Free article. French. No abstract available.
[An array of microfabricated pillars to study cell migration].
Buguin A, Chavrier P, Ladoux B, du Roure O, Saez A, Silberzan P. Buguin A, et al. Med Sci (Paris). 2005 Aug-Sep;21(8-9):765-7. doi: 10.1051/medsci/2005218-9765. Med Sci (Paris). 2005. PMID: 16115464 French.
We have developed a new force sensor made of a dense array of soft micron-size pillars microfabricated using microelectronics techniques. This approach uses elastomeric substrates that are micropatterned by using a combination of hard and soft lithography. Tr …

Orientation and polarity in collectively migrating cell structures: statics and dynamics.
Reffay M, Petitjean L, Coscoy S, Grasland-Mongrain E, Amblard F, Buguin A, Silberzan P. Reffay M, et al. Biophys J. 2011 Jun 8;100(11):2566-75. doi: 10.1016/j.bpj.2011.04.047. Biophys J. 2011. PMID: 21641301 Free PMC article.
From a dynamical point of view, cells entering a finger gradually polarize on timescales that depend upon their particular initial position. Selective laser nanosurgery of the leader lamellipodium shows not only that these structures need a leader to progress …
