Pain killing neurons from stem cells

“To make the pain-killing neurons, we [at the University of Sydney, Australia] take human stem cells obtained from skin or blood cells then turned into pluripotent cells, and culture them for four weeks,” . . . Each week we change the growth factors and drugs in the culture, and after four weeks we have almost pure (95 percent) pain-killing neurons.”  Since this study was done in mice, presumably the researchers used mice stem cells, and then implanted them in the animals’ spinal cord.  It appeared that the fix was permanent.
