Epithelial layer fluidization by curvature-induced unjamming
Margherita De Marzio, Amit Das, Jeffrey J. Fredberg +1
The transition of an epithelial layer from a stationary, quiescent state to a highly migratory, dynamic state is required for wound healing, development, and regeneration. This tra…
Active emulsions in living cell membranes driven by contractile stresses and transbilayer coupling
Suvrajit Saha, Amit Das, Chandrima Patra +4
The spatiotemporal organisation of proteins and lipids on the cell surface has direct functional consequences for signaling, sorting and endocytosis. Earlier studies have shown tha…
Active Segregation Dynamics in the Living Cell
Ajay Bansal, Amit Das, Madan Rao
In this paper, we bring together our efforts in identifying and understanding nonequilibrium phase segregation driven by active processes in the living cell, with special focus on…
Controlled neighbor exchanges drive glassy behavior, intermittency and cell streaming in epithelial tissues
Amit Das, Srikanth Sastry, Dapeng Bi
Cell neighbor exchanges are integral to tissue rearrangements in biology, including development and repair. Often these processes occur via topological T1 transitions analogous to…
Mechanical heterogeneity in tissues promotes rigidity and controls cellular invasion
Xinzhi Li, Amit Das, Dapeng Bi
We study the influence of cell-level mechanical heterogeneity in epithelial tissues using a vertex-based model. Heterogeneity in single cell stiffness is introduced as a quenched r…
A biological tissue-inspired tunable photonic fluid
Xinzhi Li, Amit Das, Dapeng Bi
Inspired by how cells pack in dense biological tissues, we design 2D and 3D amorphous materials which possess a complete photonic band gap. A physical parameter based on how cells…
