This paper presents a general theoretical model of the transmission of forces in disordered fiber networks generated by an active unit such as a molecular motor. The work shows that irrespective of whether the ... WebDec 8, 2024 · To further investigate the effects of the cell-ECM mechanical coupling on collectively polarized invading cells, we also develop a novel active-particle-on-network model, which explicitly considers the mechanical coupling between distant cells through ECM network-mediated active force propagation [ 19, 21 – 23, 29, 30 ], rather than …
