Tissue shape from cell-scale active tensions
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Connecting cell behavior to tissue shape and mechanics is a key challenge in the physics of morphogenesis. Cytoskeletal turnover precludes a fixed reference state, and tensions are…
Emergent Elasticity and Quasiconformal Flow in Active Solids
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
A constitutive relation between stress and strain relative to a reference state is the basic assumption of elasticity theory. However, in living matter, force generation is governe…
A Geometric Tension Dynamics Model of Epithelial Convergent Extension
Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman
Convergent extension of epithelial tissue is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelia…
A "morphogenetic action" principle for 3D shape formation by the growth of thin sheets
Dillon J. Cislo, Anastasios Pavlopoulos, Boris I. Shraiman
How does growth encode form in developing organisms? Many different spatiotemporal growth profiles may sculpt tissues into the same target 3D shapes, but only specific growth patte…
Fluctuations can induce local nematic order and extensile stress in monolayers of motile cells
Farzan Vafa, Mark J. Bowick, Boris I. Shraiman +1
Recent experiments in various cell types have shown that two-dimensional tissues often display local nematic order, with evidence of extensile stresses manifest in the dynamics of…
Multi-defect Dynamics in Active Nematics
Farzan Vafa, Mark J. Bowick, M. Cristina Marchetti +1
Recent experiments and numerical studies have drawn attention to the dynamics of active nematics. Two-dimensional active nematics flow spontaneously and exhibit spatiotemporal chao…
