Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.
If they can perfect the saftey switch they talk about in the article. Then maybe stem cells for the brain will be like vitamins. Cause damage to like the blood brain barrier is hard to detect, but seems to be present in a decent number of “syndromes”. Like autism for one. It would be nice if they understood the why and how’s, but that could be decades away.
