Executive Industry Relevance

Three-dimensional co-culture spheres of astrocytes and neurons provide a physiologically relevant platform for interrogating synapse formation and neural network integration. This system enables predictive modeling of neurodevelopmental and neurodegenerative mechanisms, supporting early-stage target validation and mechanistic de-risking in CNS drug discovery. The approach enhances translational continuity by bridging in vitro findings with disease-relevant neural circuitry.
