Executive Industry Relevance

The transient middle cerebral artery occlusion (MCAO) model in mice provides a robust, reproducible platform for evaluating ischemic stroke mechanisms and candidate neuroprotective agents. This model enables quantitative assessment of lesion progression and functional outcomes, supporting predictive confidence in early-stage CNS therapeutic discovery. Its integration of neuroimaging and behavioral endpoints enhances translational continuity from preclinical research to clinical hypothesis generation.
