Cytoplasmic Viscosity is a Potential Biomarker for Metastatic Breast Cancer Cells
Marie Dessard, Jean-Baptiste Manneville, Jean-François Berret
Cellular microrheology has shown that cancer cells with high metastatic potential are softer compared to non-tumorigenic normal cells. These findings rely on measuring the apparent…
Morphogenesis of Gastrovascular Canal Network in Aurelia Jellyfish: possible mechanisms
Song Solène, Stanislaw Zukowski, Camille Gambini +4
Patterns in biology can be considered as predetermined, or arising from a self-organizing instability. Variability in the pattern can thus be interpreted as a trace of an instabili…
Rebound and scattering of motile Chlamydomonas algae in confined chambers
Albane Théry, Yuxuan Wang, Mariia Dvoriashyna +3
Motivated by recent experiments demonstrating that motile algae get trapped in draining foams, we study the trajectories of microorganisms confined in model foam channels (section…
Shape-velocity correlation defines polarization in migrating cell simulations
Gilberto L. Thomas, Ismael Fortuna, Gabriel C. Perrone +2
Cell migration plays essential roles in development, wound healing, diseases, and in the maintenance of a complex body. Experiments in collective cell migration generally measure q…
3D shape of epithelial cells on curved substrates
Nicolas Harmand, Sylvie Hénon
It is widely recognized that the shape of epithelial cells is determined by the tension generated by the actomyosin cortex and the adhesion of cells to the substrate and to each ot…
The first digestive movements in the embryo are mediated by mechanosensitive smooth muscle calcium waves
Nicolas Chevalier
Peristalsis enables transport of the food bolus in the gut. Here, I show by dynamic ex-vivo intra-cellular calcium imaging on living embryonic gut transverse sections that the most…
