Hierarchical self-organization of cytoskeletal active networks.
The structural reorganization of the actin cytoskeleton is facilitated through the action of motor proteins that crosslink the actin filaments and transport them relative to each other. Here, we present a combined experimental-computational study that probes the dynamic evolution of mixtures of actin filaments and clusters of myosin motors. While on small spatial and temporal scales the system ...
متن کاملCollective Dynamics of Active Cytoskeletal Networks
Self organization mechanisms are essential for the cytoskeleton to adapt to the requirements of living cells. They rely on the intricate interplay of cytoskeletal filaments, crosslinking proteins and molecular motors. Here we present an in vitro minimal model system consisting of actin filaments, fascin and myosin-II filaments exhibiting pulsatile collective dynamics and superdiffusive transpor...
متن کاملActive multi-point microrheology of cytoskeletal networks
Active microrheology is a valuable tool to determine viscoelastic properties of polymer networks. Observing the response of the beads to the excitation of a reference leads to dynamic and morphological information of the material. In this work we present an expansion of the well-known active two-point microrheology. By measuring the response of multiple particles in a viscoelastic medium in res...
متن کاملPattern formation in multiplex networks
The advances in understanding complex networks have generated increasing interest in dynamical processes occurring on them. Pattern formation in activator-inhibitor systems has been studied in networks, revealing differences from the classical continuous media. Here we study pattern formation in a new framework, namely multiplex networks. These are systems where activator and inhibitor species ...
متن کاملTowards a Universal Constructor IV: Plant Cytoskeletal Pattern Formation
Rather than being ‘random’ viscous fluids, it has been suggested that red cell cytomechanics demonstrate the flows of membrane lipids and the cytoplasm are spatio-temporally organised by convective and shear-driven mechanisms when cells are metabolically active 1-4 . Feedback between the cortical protein and phospholipid was shown to permit membrane flows to dictate the arrangement of cytoskele...
