Multiciliated cells use filopodia to probe tissue mechanics during epithelial integration in vivo

Autor: Guilherme Ventura, Aboutaleb Amiri, Raghavan Thiagarajan, Mari Tolonen, Amin Doostmohammadi, Jakub Sedzinski

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-15 (2022)

Cell integration is a critical process in shaping complex tissues. Ventura and Amiri et al. reveal how multiciliated cells exert forces using filopodia to probe and remodel the neighboring cells, facilitating the formation of a susceptible environmen

Multi-scale computational study of the mechanical regulation of cell mitotic rounding in epithelia.

Autor: Ali Nematbakhsh, Wenzhao Sun, Pavel A Brodskiy, Aboutaleb Amiri, Cody Narciso, Zhiliang Xu, Jeremiah J Zartman, Mark Alber

Publikováno v: PLoS Computational Biology, Vol 13, Iss 5, p e1005533 (2017)

Mitotic rounding during cell division is critical for preventing daughter cells from inheriting an abnormal number of chromosomes, a condition that occurs frequently in cancer cells. Cells must significantly expand their apical area and transition fr

Emergent chirality in active solid rotation of pancreas spheres

Autor: Tzer Han Tan, Aboutaleb Amiri, Irene Seijo-Barandiarán, Michael F. Staddon, Anne Materne, Sandra Tomas, Charlie Duclut, Marko Popović, Anne Grapin-Botton, Frank Jülicher

Collective cell dynamics play a crucial role in many developmental and physiological contexts. While two-dimensional (2D) cell migration has been widely studied, how three-dimensional (3D) geometry and topology interplay with collective cell behavior

Coarse-grained curvature tensor on polygonal surfaces

Autor: Charlie Duclut, Aboutaleb Amiri, Joris Paijmans, Frank Jülicher

Publikováno v: SciPost Physics Core. 5

Using concepts from integral geometry, we propose a definition for a local coarse-grained curvature tensor that is well-defined on polygonal surfaces. This coarse-grained curvature tensor shows fast convergence to the curvature tensor of smooth surfa

Unifying polar and nematic active matter:Emergence and co-existence of half-integer and full-integer topological defects

Autor: Aboutaleb Amiri, Romain Mueller, Amin Doostmohammadi

Publikováno v: Amiri, A, Mueller, R & Doostmohammadi, A 2022, ' Unifying polar and nematic active matter : Emergence and co-existence of half-integer and full-integer topological defects ', Journal of Physics A: Mathematical and Theoretical, vol. 55, no. 9, 094002 . https://doi.org/10.1088/1751-8121/ac4abe

The presence and significance of active topological defects is increasingly realised in diverse biological and biomimetic systems. We introduce a continuum model of polar active matter, based on conservation laws and symmetry arguments, that recapitu

Mechanics of cell integration in vivo

Autor: Amin Doostmohammadi, Guilherme B. Ventura, Raghavan Thiagarajan, Mari Tolonen, Jakub Sedzinski, Aboutaleb Amiri

Publikováno v: Ventura, G B, Amiri, A, Thiagarajan, R, Tolonen, M, Doostmohammadi, A & Sedzinski, J 2021, ' Mechanics of cell integration in vivo ', bioRxiv . https://doi.org/10.1101/2021.11.18.469090

During embryonic development, regeneration and homeostasis, cells have to physically integrate into their target tissues, where they ultimately execute their function. Despite a significant body of research on how mechanical forces instruct cellular

Deformation of a constrained thin elastic sheet over a flat surface due to gravity

Autor: Maniya Maleki, Aboutaleb Amiri, S. Mahmoud Hashemi

Publikováno v: International Journal of Non-Linear Mechanics

Using the theory of elasticity for large deflections, we obtain the differential equation describing the equilibrium shape of an elastica subjected to several distinct boundary conditions. In our study, one side of the elastica is assumed to be clamp

Pseudomonas aeruginosa is a ubiquitous bacterium that survives in many environments, including as an acute and chronic pathogen in humans. Substantial evidence shows that P. aeruginosa behavior is affected by its motility, and appendages known as fla

Reversals and collisions optimize protein exchange in bacterial swarms

Publikováno v: Physical review. E, vol 95, iss 3-1

Swarming groups of bacteria coordinate their behavior by self-organizing as a population to move over surfaces in search of nutrients and optimal niches for colonization. Many open questions remain about the cues used by swarming bacteria to achieve
