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…
A Mechanistic Model of the Organization of Cell Shapes in Epithelial Tissues
Kanaya Malakar, Rafael I. Rubenstein, Dapeng Bi +1
The organization of cells within tissues plays a vital role in various biological processes, including development and morphogenesis. As a result, understanding how cells self-orga…
Bridging the Gap Between Collective Motility and Epithelial-Mesenchymal Transitions through the Active Finite Voronoi Model
Junxiang Huang, Herbert Levine, Dapeng Bi
We introduce an active version of the recently proposed finite Voronoi model of epithelial tissue. The resultant Active Finite Voronoi (AFV) model enables the study of both conflue…
Cell Division and Motility Enable Hexatic Order in Biological Tissues
Yiwen Tang, Siyuan Chen, Mark J. Bowick +1
Biological tissues transform between solid-like and liquid-like states in many fundamental physiological events. Recent experimental observations further suggest that in two-dimens…
Network physics of attractive colloidal gels: Resilience, Rigidity, and Phase Diagram
Mohammad Nabizadeh, Farzaneh Nasirian, Xinzhi Li +6
Attractive colloidal gels exhibit solid-like behavior at vanishingly small fractions of solids, owing to ramified space-spanning networks that form due to particle-particle interac…
Discontinuous rigidity transition associated with shear jamming in granular simulations
Varghese Babu, H. A Vinutha, Dapeng Bi +1
We investigate the rigidity transition associated with shear jamming in frictionless, as well as frictional, disk packings in the quasi-static regime and at low shear rates. For fr…
