Journal ArticleDOI
Time-dependent traction force microscopy for cancer cells as a measure of invasiveness
Valentina Peschetola,Valérie M. Laurent,Alain Duperray,Alain Duperray,Richard Michel,Davide Carlo Ambrosi,Luigi Preziosi,Claude Verdier +7 more
TL;DR: It is found that the outliers of the traction stresses can be an effective indicator to distinguish cancer cell lines of different invasivity, and conjecture that this kind of analysis can be useful to classify cancer cell invasiveness.
Journal ArticleDOI
Traction patterns of tumor cells
TL;DR: The shear stress obtained by numerical integration provides quantitative insight of the traction field and is a promising tool to investigate the spatial pattern of force per unit surface generated in cell motion, particularly in the case of such cancer cells.
Journal ArticleDOI
Prediction of traction forces of motile cells.
Clément Roux,Clément Roux,Alain Duperray,Alain Duperray,Valérie M. Laurent,Valérie M. Laurent,Richard Michel,Richard Michel,Valentina Peschetola,Valentina Peschetola,Claude Verdier,Claude Verdier,Jocelyn Etienne,Jocelyn Etienne +13 more
TL;DR: A rheological model of actomyosin linking tension, deformation and myosin activity is validated and the basic pattern of traction forces is robustly predicted by the model and fixed parameters as a function of current geometry only.
Journal ArticleDOI
Mathematical framework for traction force microscopy
Richard Michel,Valentina Peschetola,Valentina Peschetola,Guido Vitale,Jocelyn Etienne,Alain Duperray,Davide Carlo Ambrosi,Luigi Preziosi,Claude Verdier +8 more
TL;DR: In this paper, an abstract framework was proposed to formulates the inverse problem as a constrained minimization problem, and two methods, the adjoint method (AM) and the Fourier Transform Traction Cytometry (FTTC), were derived from this framework.
Journal ArticleDOI
Traction forces of cancer cells
Valentina Peschetola,Valérie M. Laurent,Alain Duperray,Luigi Preziosi,Davide Carlo Ambrosi,Claude Verdier +5 more
TL;DR: This research aims at understanding the forces developped by different cancer cells of moderate to high invasiveness in order to investigate their contractility as well as the adhesion molecules necessary for cell migration.
