Stem cells reverse stroke damage in mice
The gist
University of Zurich researchers reported stem cell transplants regenerated stroke-damaged brain tissue in mice.
The work is early animal research, but it targets damage doctors currently cannot repair.
How it unfolded
- Sep 21, 2026University of Zurich researchers reported that stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function, and also improved blood vessels, inflammation, and the blood-brain barrier.
- Sep 22, 2026Yahoo News reported that transplanted human stem cells survived in mouse brains damaged by stroke, developed into neurons, and improved motor performance on behavioral tests; the transplanted cells also promoted blood vessel growth, reduced inflammation, and improved blood-brain barrier integrity.
