Personalized brain transplants: Skin cells to brain cells achieved in primates
In many ways the Holy Grail in transplantation is to convert a body’s own cells into stem cells, turn those into neural cells, and then integrate them into functional circuitry within the brain. Until now, only pieces of that puzzle have been possible. Su-Chun Zhang, who was the first to convert embryonic stem cells, and later induced pluripotent stem cells into neurons, has now demonstrated that these iPSCs can be successfully introduced into the brain — in other words, he has achieved autologous, tumorless, indefinite and functional neuro-transplantation.
