简介：
Overview
This study presents a method for creating an embolic middle cerebral artery occlusion model using homologous blood clots in adult rats. This model effectively simulates human ischemic stroke, making it valuable for preclinical research on thrombolytic therapies.
Key Study Components
Area of Science
