Entropy Production Rate is Maximized in Non-Contractile Actomyosin
Daniel S. Seara, Vikrant Yadav, Ian Linsmeier +5
The actin cytoskeleton is an active semi-flexible polymer network whose non-equilibrium properties coordinate both stable and contractile behaviors to maintain or change cell shape…
Propagating stress waves during epithelial expansion
Shiladitya Banerjee, Kazage J. C. Utuje, M. Cristina Marchetti
Coordinated motion of cell monolayers during epithelial wound healing and tissue morphogenesis involves mechanical stress generation. Here we propose a model for the dynamics of ep…
Controlling cell-matrix traction forces by extracellular geometry
Shiladitya Banerjee, M. Cristina Marchetti
We present a minimal continuum model of strongly adhering cells as active contractile isotropic media and use the model to study the effect of the geometry of the adhesion patch in…
Contractile stresses in cohesive cell layers on finite-thickness substrates
Shiladitya Banerjee, M. Cristina Marchetti
Using a minimal model of cells or cohesive cell layers as continuum active elastic media, we examine the effect of substrate thickness and stiffness on traction forces exerted by s…
Scaling of Traction Forces with Size of Cohesive Cell Colonies
Aaron F. Mertz, Shiladitya Banerjee, Yonglu Che +6
To understand how the mechanical properties of tissues emerge from interactions of multiple cells, we measure traction stresses of cohesive colonies of 1-27 cells adherent to soft…
Generic phases of cross-linked active gels: Relaxation, Oscillation and Contractility
Shiladitya Banerjee, Tanniemola B. Liverpool, M. Cristina Marchetti
We study analytically and numerically a generic continuum model of an isotropic active solid with internal stresses generated by non-equilibrium `active' mechano-chemical reactions…
Instabilities and Oscillations in Isotropic Active Gels
Shiladitya Banerjee, M. Cristina Marchetti
We present a generic formulation of the continuum elasticity of an isotropic crosslinked active gel. The gel is described by a two-component model consisting of an elastic network…
