most likely its referring to stem cells. They have done it on animals, but not likely on humans in the coming years, years of testing is required as well. I think it will benefit people with neurodegenerative diseases more than to neuropathy, since there are so many causes of neuropathy(not many are known). Some systemic causes like autoimmune and diabetes can reverse something like neuron transplants, because the damage caused by these diseases is still present even if the neurons are replaced. If they come out with multi-pronged treatment, that would make it more effective.
