Real-Time In Vitro Imaging of Axonal Branching in Mouse Cortical Neurons

Executive Industry Relevance

Real-time in vitro imaging of axonal branching in mouse cortical neurons provides a quantitative platform for interrogating neuronal morphogenesis and membrane trafficking. This approach enables mechanistic de-risking of neurodevelopmental targets by directly visualizing the effects of extracellular cues such as netrin-1 on axonal architecture. The methodology supports predictive confidence in early discovery and target validation for neurobiology-focused portfolios.
