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.
They have a point. Mouse model research translation to human disease has a poor track record. Mouse model labs spin in circles between models and never try to translate into humans. Some diseases stall for decades in models.
The mouse’s brain plasticity is orders of magnitude higher than a human’s.
