I would be surprised if this ever comes to reality. It's the FDA, ADA and other pharmaceutical interests that are keeping this from going forward. They make lots of money poisoning us with mercury fillings, estrogen-laden fillings, root canals, fake implants, dentures, etc...
We have to get rid of our current system before we will be allowed cutting edge tech such as this. The elite probably already has access to all cutting edge tech.
I am surprised that the stem cell tech is available for cartilage and joints from Dr. John Lieurance and his partner in FL.
