Scientists Reverse Stroke Damage Using Stem Cells in Breakthrough Study

Scientists transplanted iPSC-derived neural progenitor cells into stroke-damaged mouse brains one week after injury.

The cells survived, mostly turned into neurons, and helped rebuild neural connections while boosting blood vessel growth and lowering inflammation.

Treated mice showed better coordination and movement, suggesting meaningful brain repair after stroke may be possible.

The findings from the University of Zurich and the University of Southern California point to future stem cell therapies for stroke recovery.
