Human regeneration, he said, is likely still in the future, but not too far off it's possible one of his current graduate students or postdoctoral researchers will crack it, and limb regeneration will be a part of the medical toolkit. While GRID cells don't regenerate as well in mice as in salamanders, finding them in mammals was significant.
