Geometric Confinement Reveals Scale-Free Velocity Correlations in Epithelial Cell Monolayer
Guillaume Duprez, Mélina Durande, François Graner +1
Collective cell flows are a hallmark of tissue dynamics in development, wound healing, and various diseases. Here, we perform experiments on epithelial MDCK cell monolayers, over t…
Linear correlation between active and resistive stresses informs on force generation and stress transmission in adherent cells
Hélène Delanoë-Ayari, Nicolas Bouchonville, Marie Courçon +1
Animal cells are active, contractile objects. While bioassays address the molecular characterization of cell contractility, the mechanical characterization of the active forces in…
Fast determination of coarse grained cell anisotropy and size in epithelial tissue images using Fourier transform
M. Durande, S. Tlili, T. Homan +3
Mechanical strain and stress play a major role in biological processes such as wound healing or morphogenesis. To assess this role quantitatively, fixed or live images of tissues a…
Collective cell migration without proliferation: density determines cell velocity and wave velocity
S. Tlili, E. Gauquelin, B. Li +4
Collective cell migration contributes to embryogenesis, wound healing and tumor metastasis. Cell monolayer migration experiments help understanding what determines the movement of…
Yield stress and elasticity influence on surface tension measurements
Loren Jørgensen, Marie Le Merrer, Hélène Delanoë-Ayari +1
We have performed surface tension measurements on carbopol gels of different concentrations and yield stresses. Our setup, based on the force exerted by a capillary bridge on two p…
Measuring accurately liquid and tissue surface tension with a compression plate tensiometer
Abbas Mgharbel, Hélène Delanoë-Ayari, Jean-Paul Rieu
Apparent tissue surface tension allows the quantification of cell-cell cohesion and was reported to be a powerful indicator for the cellular rearrangements that take place during e…
