20.500.12556/RUL-185988 Junctional-fluctuation-mediated fluidization of multi-phase-field epithelial monolayers We analyze a multi-phase-field model for an epithelial monolayer with pairwise adhesions between neighboring cells following an Ornstein-Uhlenbeck process, representing the stochastic turnover of junctional molecular motors. These fluctuations in junctional adhesion result in rearrangements in the tissue, fluidizing it and producing diffusive cell motion. Similar junctional fluctuations have proven a very useful tool in the vertex model literature, and we hope they will be equally helpful to the multi-phase-field model approach. Moreover, we observe that the cells' effective diffusion coefficient depends nonmonotonically on the persistence time of the fluctuations, confirming results previously observed in the vertex model. biophysics cell mechanics epithelial tissues biofizika celična mehanika epitelijsko tkivo true false true Angleški jezik Slovenski jezik Članek v reviji 2026-08-25 09:55:28 2026-08-25 09:55:29 2026-08-26 04:13:04 0000-00-00 00:00:00 2026 0 0 Str. 024407-1-024407-6 iss. 2 Vol. 114 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577.3 2470-0045 10.1103/lbph-g5kd 288748035 https://journals.aps.org/pre/abstract/10.1103/lbph-g5kd 1 f08992f9-a059-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245025 lbph-g5kd.pdf lbph-g5kd.pdf 1 A56445DD1DA658CF3E00FA25BF065D20 03e050942166d119c1b72ed99f9b8d5b658ced1c9be929936c051eb8bb5a0d19 1c59b1dd-a05a-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245026 Fakulteta za matematiko in fiziko 0 0 0
