Regenerative medicine may someday arrive when they learn more about stem cells and genetics, but for now stimulating receptors that have evolved to have protective effects will in my opinion, at best, reduce some of the detrimental effects of disease and/or aging, one clinical trial at a time.
Personally, I will keep my eye on the science, one step at a time, and try not to count my chickens before they hatch. Rett syndrome is the next step.
