ex vivoでマウス神経上皮における単一細胞分裂のライブイメージング

Executive Industry Relevance

Direct ex vivo live imaging of single cell divisions in mouse neuroepithelium enables high-resolution tracking of cell fate, signaling response, and subcellular events in a physiologically relevant context. This capability supports mechanistic de-risking and predictive confidence at early discovery inflection points, particularly for neurodevelopmental target validation and pathway interrogation. The approach is adaptable for diverse genetic backgrounds and fluorescent markers, enhancing its portfolio-wide utility in preclinical neuroscience R&D.
