Delay-facilitated self-assembly in compartmentalized systems
Severin Angerpointner, Richard Swiderski, Erwin Frey
Self-assembly processes in biological and synthetic biomolecular systems are often governed by the spatial separation of biochemical processes. While previous work has focused on o…
Active gel theory for cell migration with two myosin isoforms
Nils O. Winkler, Oliver M. Drozdowski, Falko Ziebert +1
Myosin II molecular motors slide actin filaments relatively to each other and are essential for force generation, motility and mechanosensing in animal cells. For non-muscle cells,…
Cell bulging and extrusion in a three-dimensional bubbly vertex model for curved epithelial sheets
Oliver M. Drozdowski, Büşra Kocameşe, Kim E. Boonekamp +2
Cell extrusion is an essential mechanism for controlling cell density in epithelial tissues. Another essential element of epithelia is curvature, which is required to achieve compl…
Self-organized homogenization of flow networks
Julien Bouvard, Swarnavo Basu, Charlott Leu +4
From the vasculature of animals to the porous media making up batteries, the core task of flow networks is to transport solutes and perfuse all cells or media equally with resource…
Acoustic signaling enables collective perception and control in active matter systems
Alexander Ziepke, Ivan Maryshev, Igor S. Aranson +1
Emergent cooperative functionality in active matter systems plays a crucial role in various applications of active swarms, ranging from pollutant foraging and collective threat det…
Coarsening dynamics of chemotactic aggregates
Henrik Weyer, David Muramatsu, Erwin Frey
Auto-chemotaxis, the directed movement of cells along gradients in chemicals they secrete, is central to the formation of complex spatiotemporal patterns in biological systems. Sin…
Chemotaxis-induced phase separation
Henrik Weyer, David Muramatsu, Erwin Frey
Chemotaxis allows single cells to self-organize at the population level, as classically described by Keller-Segel models. We show that chemotactic aggregation can be understood usi…
Phase Separation on Deformable Membranes: interplay of mechanical coupling and dynamic surface geometry
Antonia Winter, Yuhao Liu, Alexander Ziepke +2
The self-organization of proteins into enriched compartments and the formation of complex patterns are crucial processes for life on the cellular level. Liquid-liquid phase separat…
Active gel model for one-dimensional cell migration coupling actin flow and adhesion dynamics
Valentin Wössner, Oliver M. Drozdowski, Falko Ziebert +1
Migration of animal cells is based on the interplay between actin polymerization at the front, adhesion along the cell-substrate interface, and actomyosin contractility at the back…
Morphological instability at topological defects in a three-dimensional vertex model for spherical epithelia
Oliver M. Drozdowski, Ulrich S. Schwarz
Epithelial monolayers are a central building block of complex organisms. Topological defects have emerged as important elements for single cell behavior in flat epithelia. Here we…
Supramolecular assemblies in active motor-filament systems: micelles, bilayers, and foams
Filippo De Luca, Ivan Maryshev, Erwin Frey
Active matter systems evade the constraints of thermal equilibrium, leading to the emergence of intriguing collective behavior. A paradigmatic example is given by motor-filament mi…
Monitoring cis-to-trans isomerization of azobenzene using Brillouin microscopy
Zhe Wang, Qiyang Jiang, Chantal Barwig +3
Brillouin spectroscopy is commonly used to study the acoustic properties of materials. Here we explored its feasibility in studying the photoinduced isomerization of azobenzene. Th…
Reaction-driven Diffusiophoresis of Liquid Condensates: Mechanisms for Intra-cellular Organization
Gregor Häfner, Marcus Müller
The cellular environment, characterized by its intricate composition and spatial organization, hosts a variety of organelles, ranging from membrane-bound ones to membraneless struc…
On the emergence of memory in equilibrium versus non-equilibrium systems
Xizhu Zhao, David Hartich, Aljaž Godec
Experiments often probe observables that correspond to low-dimensional projections of highdimensional dynamics. In such situations distinct microscopic configurations become lumped…
Enzyme-enriched condensates show self-propulsion, positioning, and coexistence
Leonardo Demarchi, Andriy Goychuk, Ivan Maryshev +1
Enzyme-enriched condensates can organize the spatial distribution of their substrates by catalyzing non-equilibrium reactions. Conversely, an inhomogeneous substrate distribution i…
Anomalous Collective Dynamics of Auto-Chemotactic Populations
Jasper van der Kolk, Florian Rasshofer, Richard Swiderski +3
While the role of local interactions in nonequilibrium phase transitions is well studied, a fundamental understanding of the effects of long-range interactions is lacking. We study…
Geometry-induced patterns through mechanochemical coupling
Laeschkir Würthner, Andriy Goychuk, Erwin Frey
Intracellular protein patterns regulate a variety of vital cellular processes such as cell division and motility, which often involve dynamic changes of cell shape. These changes i…
Coarsening and wavelength selection far from equilibrium: a unifying framework based on singular perturbation theory
Henrik Weyer, Fridtjof Brauns, Erwin Frey
Intracellular protein patterns are described by (nearly) mass-conserving reaction-diffusion systems. While these patterns initially form out of a homogeneous steady state due to th…
Bridging scales in a multiscale pattern-forming system
Laeschkir Würthner, Fridtjof Brauns, Grzegorz Pawlik +4
Self-organized pattern formation is vital for many biological processes. Reaction-diffusion models have advanced our understanding of how biological systems develop spatial structu…
Length Regulation Drives Self-Organization in Filament-Motor Mixtures
Moritz Striebel, Fridtjof Brauns, Erwin Frey
Cytoskeletal networks form complex intracellular structures. Here we investigate a minimal model for filament-motor mixtures in which motors act as depolymerases and thereby regula…
