Multi-Scale Modeling for Cell Fate Specification During Regeneration and Development

The document discussed multi-scale modeling approaches to understand cell fate specification during tissue regeneration and early embryo development. For skin wound healing, a model was developed to explore mechanisms reducing scarring, focusing on epidermis-dermis interactions. Key findings included the importance of signaling factors for dermal stability, the role of re-epithelialization in reducing wound size, and the impact of fibrin clot density on scar phenotype. In early embryo development, a multi-scale model was used to study gene expression and spatial arrangement at the single-cell level, revealing that Epha4/Ephrinb2-driven cell adhesion and timely fibroblast growth factor regulation are crucial for proper embryo organization and cell fate determination.
