Imagine a future where a massive brain injury is not a life sentence, but a reversible condition. A world where stroke survivors don’t spend the rest of their lives fighting to reclaim fragments of motor skills or cognition—but instead regrow the lost brain tissue itself. Thanks to a new breakthrough from Zurich researchers, that future is unfolding before our eyes.
In mice, human neural stem cells have been transplanted into damaged brain regions, surviving, integrating, and even communicating with existing brain circuits. Within weeks, the animals recovered motor functions lost to stroke. Inflammation was reduced, blood–brain barriers restored, new blood vessels formed, and damaged neurons regenerated. In short: the brain began to heal itself.
