The role of the cytoskeleton in volume regulation and beading transitions in PC12 neurites
Pablo Fernandez, Pramod A. Pullarkat
We present investigations on volume regulation and beading shape transitions in PC12 neurites conducted using a flow-chamber technique. By disrupting the cell cytoskeleton with spe…
Inelastic mechanics of sticky biopolymer networks
Lars Wolff, Pablo Fernandez, Klaus Kroy
We propose a physical model for the nonlinear inelastic mechanics of sticky biopolymer networks with potential applications to inelastic cell mechanics. It consists in a minimal ex…
A unit-cell approach to the nonlinear rheology of biopolymer solutions
Pablo Fernandez, Steffen Grosser, Klaus Kroy
We propose a nonlinear extension of the standard tube model for semidilute solutions of freely-sliding semiflexible polymers. Non-affine filament deformations at the entanglement s…
Single cell mechanics: stress stiffening and kinematic hardening
Pablo Fernández, Albrecht Ott
Cell mechanical properties are fundamental to the organism but remain poorly understood. We report a comprehensive phenomenological framework for the nonlinear rheology of single f…
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…
A master relation defines the nonlinear viscoelasticity of single fibroblasts
Pablo Fernandez, Pramod A. Pullarkat, Albrecht Ott
Cell mechanical functions like locomotion, contraction and division are controlled by the cytoskeleton, a dynamic biopolymer network whose mechanical properties remain poorly under…
