Sviluppo di un modello 3D ingegnerizzato basato su seta-collagene di tessuto neurale polarizzato

Executive Industry Relevance

This 3D polarized neural tissue model supports early discovery by enabling mechanistic de-risking of neuronal targets through physiologically relevant axonal network formation. The silk-collagen scaffold system provides a reproducible platform for evaluating compound effects on neuronal connectivity and network integrity. It bridges in vitro simplicity with in vivo-like tissue organization, improving predictive confidence in preclinical target validation.
