Hydrodynamics in a villi-patterned channel due to pendular-wave activity

Rohan Vernekar, Faisal Ahmad, Martin Garic, Dácil Idaira Yánez Martín, Claude Loverdo, Stéphane Tanguy, Clément de Loubens

Inspired by the motility of small intestine, we investigate the flow generated by a propagating pendular-wave along the walls of a symmetric 2D channel lined with elongated villi-like microstructures. The rigid villi follow simple harmonic axial motion, but with a phase lag to their neighbours,…

Noninvasive characterization of oocyte deformability in microconstrictions

Lucie Barbier, Rose Bulteau, Behnam Rezaei, Thomas Panier, Gaëlle Letort, Elsa Labrune, Marie-Hélène Verlhac, Franck Vernerey, Clément Campillo, Marie-Emilie Terret

Oocytes naturally present mechanical defects that hinder their development after fertilization. Thus, in the context of assisted reproduction, oocyte selection based on their mechanical properties has great potential to improve the quality of the resulting embryos and the success rate of these…

Cooperative nutrient scavenging is an evolutionary advantage in cancer

Gizem Guzelsoy, Setiembre D Elorza, Manon Ros, Logan T Schachtner, Makiko Hayashi, Spencer Hobson-Gutierrez, Parker Rundstrom, Julia S Brunner, Ray Pillai, William E Walkowicz, Lydia W S Finley, Maxime Deforet, Thales Papagiannakopoulos, Carlos Carmona-Fontaine

The survival of malignant cells within tumours is often seen as depending on ruthless competition for nutrients and other resources1,2. Although competition is certainly critical for tumour evolution and cancer progression, cooperative interactions within tumours are also important, albeit poorly…
