Inducing Ischemic Stroke via Middle Cerebral Artery Occlusion Using a Thread Bolt

Executive Industry Relevance

Robust preclinical models of ischemic stroke are essential for evaluating neuroprotective strategies and understanding mechanisms of neuronal injury. The middle cerebral artery occlusion (MCAO) thread bolt technique provides a reproducible platform for hypothesis-driven target validation and mechanistic de-risking in early discovery. This model supports translational continuity from discovery through preclinical assessment, informing portfolio decisions in neurovascular research.
