We developed a hybrid continuous-discrete model to study how mechanical cues influence cell migration on elastic fiber matrices. Refinement of the model requires to represent cells as mechanosensitive networks, where adhesions and filopodia interact dynamically with the substrate. Simulations demonstrate that cells adapt their migration patterns based on substrate properties, reproducing experimentally observed behaviors such as persistent random walks and migration bias on anisotropic substrates. This work provides a mechanistic framework to explore how mechanical signals mediate long-range communication between cells, offering insights into tissue morphogenesis and collective cell dynamics. \n\nhttps://indico.math.cnrs.fr/event/16178/
