Elasticity and plasticity of epithelial gap closure
Maryam Setoudeh, Pierre A. Haas
Epiboly, during which a tissue closes around the surface of the egg, pervades animal development. This epithelial gap closure involves cell intercalations at the edge of the gap. H…
Control of lumen morphology by lateral and basal cell surfaces
Chandraniva Guha Ray, Markus Mukenhirn, Alf Honigmann +1
Across development, the morphology of fluid-filled lumina enclosed by epithelial tissues arises from an interplay of lumen pressure, mechanics of the cell cortex, and cell-cell adh…
Mesoscale properties of protein clusters determine the size and nature of liquid-liquid phase separation (LLPS)
Gonen Golani, Manas Seal, Mrityunjoy Kar +3
The observation of Liquid-Liquid Phase Separation (LLPS) in biological cells has dramatically shifted the paradigm that soluble proteins are uniformly dispersed in the cytoplasm or…
Geometry of T1 transitions in epithelia
Pierre A. Haas
The flows of tissues of epithelial cells often involve T1 transitions. These neighbour exchanges are irreversible rearrangements crossing an energy barrier. Here, by an exact geome…
Euler buckling on curved surfaces
Shiheng Zhao, Pierre A. Haas
Euler buckling epitomises mechanical instabilities: An inextensible straight elastic line buckles under compression when the compressive force reaches a critical value .…
(Un)buckling mechanics of epithelial monolayers under compression
Chandraniva Guha Ray, Pierre A. Haas
When cell sheets fold during development, their apical or basal surfaces constrict and cell shapes approach the geometric singularity in which these surfaces vanish. Here, we revea…
Mechanics of poking a cyst
Shiheng Zhao, Pierre A. Haas
Indentation tests are classical tools to determine material properties. For biological samples such as cysts of cells, however, the observed force-displacement relation cannot be e…
Buckling by disordered growth
Rahul G. Ramachandran, Ricard Alert, Pierre A. Haas
Buckling instabilities driven by tissue growth underpin key developmental events such as the folding of the brain. Tissue growth is disordered due to cell-to-cell variability, but…
Cut it out: Out-of-plane stresses in cell sheet folding of Volvox embryos
Pierre A. Haas, Stephanie S. M. H. Höhn
The folding of cellular monolayers pervades embryonic development and disease. It results from stresses out of the plane of the tissue, often caused by cell shape changes including…
Spontaneous flow instabilities of active polar fluids in three dimensions
Abhinav Singh, Quentin Vagne, Frank Jülicher +1
Active polar fluids exhibit spontaneous flow when sufficient active stress is generated by internal molecular mechanisms. This is also referred to as an active Fréedericksz transit…
The role of non-affine deformations in the elastic behavior of the cellular vertex model
Michael F. Staddon, Arthur Hernandez, Mark J. Bowick +2
The vertex model of epithelia describes the apical surface of a tissue as a tiling of polygonal cells, with a mechanical energy governed by deviations in cell shape from preferred,…
Anomalous elasticity of cellular tissue vertex model
Arthur Hernandez, Michael F. Staddon, Mark J. Bowick +2
Vertex Models, as used to describe cellular tissue, have an energy controlled by deviations of each cell area and perimeter from target values. The constrained nonlinear relation b…
Activity-induced microswimmer interactions and cooperation in one-dimensional environments
Stefania Ketzetzi, Melissa Rinaldin, Pim Dröge +2
Cooperative motion in biological microswimmers is crucial for their survival as it facilitates adhesion to surfaces, formation of hierarchical colonies, efficient motion, and enhan…
Comment on "Faceting and Flattening of Emulsion Droplets: A Mechanical Model"
Pierre A. Haas, Raymond E. Goldstein, Diana Cholakova +2
García-Aguilar et al. [Phys. Rev. Lett 126, 038001 (2021)] have shown that the deformations of "shape-shifting droplets" are consistent with an elastic model, that, unlike previous…
Shape programming lines of concentrated Gaussian curvature
D. Duffy, L. Cmok, J. S. Biggins +7
Liquid crystal elastomers (LCEs) can undergo large reversible contractions along their nematic director upon heating or illumination. A spatially patterned director within a flat L…
Salt-dependent rheology and surface tension of protein condensates using optical traps
Louise M. Jawerth, Mahdiye Ijavi, Martine Ruer +5
An increasing number of proteins with intrinsically disordered domains have been shown to phase separate in buffer to form liquid-like phases. These protein condensates serve as si…
