Cell division sets a universal flow geometry in cell layers
Tianxiang Ma, Lasse Bonn, Valeriia Grudtsyna +4
Collective flows in epithelial tissues contain a geometric backbone of vortical interfaces whose statistics exhibit hallmarks of critical percolation and conformal invariance. Yet…
Epithelia Realize Nematopolar Topological Defect Structures
Tianxiang Ma, Niels de Graaf Sousa, Valeriia Grudtsyna +2
We introduce a shape-based polar order parameter that captures the structural asymmetry of cells within epithelial monolayers. By combining bright-field imaging and traction force…
A spectrum of p-atic symmetries and defects in confluent epithelia
Lea Happel, Griseldis Oberschelp, Anneli Richter +4
Topological defects provide a unifying language to describe how orientational order breaks down in active and living matter. Considering cells as elongated particles confluent, epi…
Cellular Flow Architecture Exposes the Hidden Mechanics of Biological Matter
Tianxiang Ma, Valeriia Grudtsyna, Robin V. Bölsterli +1
Understanding how biomechanical reorganization governs key biological processes, such as morphogenesis and development, requires predictive insights into stress distributions and c…
Evidence of robust, universal conformal invariance in living biological matter
Benjamin H. Andersen, Francisco M. R. Safara, Valeriia Grudtsyna +5
Collective cellular movement plays a crucial role in many processes fundamental to health, including development, reproduction, infection, wound healing, and cancer. The emergent d…
