Mechanisms enabling efficient fountain-flow supracellular migration
Jordi Font-Reverter, Alejandro Torres-Sánchez, Guillermo Vilanova +1
In a prototypical mode of single-cell migration, retrograde cytoskeletal flow is mechanically coupled to the environment, propels the cell, and is sustained by an anterograde cytos…
Theory of active self-organization of dense nematic structures in the actin cytoskeleton
Waleed Mirza, Marco De Corato, Marco Pensalfini +3
The actin cytoskeleton is remarkably adaptable and multifunctional. It often organizes into nematic bundles such as contractile rings or stress fibers. However, how a uniform and i…
Variational formulation of active nematics: theory and simulation
Waleed Mirza, Alejandro Torres-Sánchez, Guillermo Vilanova +1
The structure and dynamics of important biological quasi-two-dimensional systems, ranging from cytoskeletal gels to tissues, are controlled by nematic order, flow, defects and acti…
Modelling fluid deformable surfaces with an emphasis on biological interfaces
Alejandro Torres-Sánchez, Daniel Millán, Marino Arroyo
Fluid deformable surfaces are ubiquitous in cell and tissue biology, including lipid bilayers, the actomyosin cortex, or epithelial cell sheets. These interfaces exhibit a complex…
