Mechanical Instabilities of Biological Tubes
Edouard Hannezo, Jean-Francois Joanny, Jacques Prost
We study theoretically the shapes of biological tubes affected by various pathologies. When epithelial cells grow at an uncontrolled rate, the negative tension produced by their di…
Membrane buckling induced by curved filaments
Martin Lenz, Daniel J. G. Crow, Jean-François Joanny
We present a novel buckling instability relevant to membrane budding in eukaryotic cells. In this mechanism, curved filaments bind to a lipid bilayer without changing its intrinsic…
Spontaneous creation of macroscopic flow and metachronal waves in an array of cilia
Boris Guirao, Jean-François Joanny
Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between c…
Osmotically Driven Shape Transformations in Axons
Pramod A. Pullarkat, Paul Dommersnes, Pablo Fernández +3
We report a cylindrical-peristaltic shape transformation in axons exposed to a controlled osmotic perturbation. The peristaltic shape relaxes and the axon recovers its original geo…
Motion of an Adhesive Gel in a Swelling Gradient: a Mechanism for Cell Locomotion
Jean-Francois Joanny, Frank Julicher, Jacques Prost
Motivated by the motion of nematode sperm cells, we present a model for the motion of an adhesive gel on a solid substrate. The gel polymerizes at the leading edge and depolymerize…
