• Resumen

  • A few months ago, Evelyn Hilton was able to ditch the walking stick she had relied on since 2014 and stand on her own two feet again. Meanwhile, Sonia Olea Coontz felt her right arm "wake up" after more than six months of it being totally paralyzed and was able to walk more easily. Both had taken part in clinical trials in which stem cells were injected into their brains at the site of an earlier stroke. This was no "Lazarus effect"; the patients didn't wake from surgery and leap dramatically from their beds, totally cured. Yet the results were a major step forward in efforts to heal damaged brains, and could lead to such treatments becoming widely available within just a few years. Here, Price investigates how cell therapies can rebuild broken brains.
