Summary

Story summary

Researchers at the University of Zurich and USC created a stem cell therapy to repair stroke-damaged brains.
Ischemic strokes, caused by restricted blood flow, represent nearly 90% of stroke cases.
Current treatments are effective only within four and a half hours after symptoms appear.
In studies, mice receiving neural stem cell transplants one week post-stroke showed significant recovery in motor skills and walking.
The therapy enhances neuron regeneration and blood-brain barrier integrity, with future research focusing on long-term effects and clinical applications.
