Researchers have developed biomimetic physics-informed neural networks (Bio-PINNs) to address numerical challenges in simulating cell-induced phase transitions within fibrous extracellular matrices. These networks employ a curriculum learning approach that gradually reveals the computational domain and uses a deformation-uncertainty proxy to concentrate data points near evolving transition layers and tether-forming regions. Bio-PINNs demonstrate improved accuracy in recovering densified phases near cell boundaries and intercellular gaps, as well as in capturing tether morphology compared to existing methods. AI
