Continuum Description of the Cytoskeleton: Ring Formation in the Cell Cortex
arXiv:q-bio/0510050 · doi:10.1103/PhysRevLett.95.258103
Abstract
Motivated by the formation of ring-like filament structures in the cortex of plant and animal cells, we study the dynamics of a two-dimensional layer of cytoskeletal filaments and motor proteins near a surface by a general continuum theory. As a result of active processes, dynamic patterns of filament orientation and density emerge via instabilities. We show that self-organization phenomena can lead to the formation of stationary and oscillating rings. We present state diagrams which reveal a rich scenario of asymptotic behaviors and discuss the role of boundary conditions.
