It is challenging to establish animal models to mimic perinatal arterial ischemic stroke. Here, we provided two approaches that precisely occlude rodent pups' distal middle cerebral artery of rodent pups at any postnatal age. One uses magnetic nanoparticles to generate platelet-rich thrombus, and the other utilizes magnetized red blood cells (mRBCs) to generate an erythrocyte-rich embolus. Both approaches result in focal cerebral ischemia followed by controllable reperfusion while requiring no arterial surgery.
