Executive Industry Relevance

Reliable preclinical stroke models are essential for evaluating therapeutic strategies targeting long-term functional recovery, especially in aged populations. The modified transcranial MCAO model enables robust assessment of both cortical and striatal injury, supporting predictive confidence in translational stroke research. This model addresses a critical inflection point in the discovery-to-preclinical continuum by improving survival rates and enabling quantifiable neurological outcomes.
