Développement d’un réseau neuronal issu d’une micro-ingénierie tissulaire à l’aide d’une micro-colonne à base d’hydrogel

Executive Industry Relevance

Hydrogel-based micro-tissue-engineered neural networks (micro-TENNs) enable the construction of anatomically inspired, three-dimensional neural models for discovery-stage neuroscience and neurotherapeutic R&D. This platform supports predictive confidence in neural pathway reconstruction and provides a scalable system for interrogating neuronal connectivity and viability. Integration of micro-TENNs into early discovery workflows advances mechanistic de-risking and translational modeling for neuroregeneration portfolios.
