Regenerating brains: stem cell transplants rewrite the horizon of stroke

In Zurich, researchers have shown that stem cell transplants can reverse damage after a stroke , promoting neuronal regeneration, restoring motor functions and even repairing blood vessels.

The study showed that in animal models, brain areas affected by oxygen deprivation during stroke were able to reconnect with new neurons and functional vascular networks. This suggests that nerve damage may not be permanent.

This evidence opens the door to future human therapies where the stroke does not leave irreversible consequences, but where mobility and cognitive functions can be recovered, at least partially.

But there are still long ways to go: ethical barriers, immunological complications, translating animal results to humans, and costs. Nevertheless, every advance brings us closer to that future.

For women, since strokes also affect quality of life and autonomy, these types of medical advances can make a difference in rehabilitation and post-stroke recovery.
