Okano’s research team, which earlier helped a mouse recover its mobility in a similar treatment, injected so-called induced pluripotent stem (iPS) cells into a paralysed marmoset, he said. The team planted four types of genes into human skin cells to create the iPS cells, according to Kyodo News.
The injection was given on the ninth day after the injury, considered the most effective timing, and the monkey started to move its limbs again within two to three weeks, Okano said.
“After six weeks, the animal had recovered to the level where it was jumping around,” he said. “It was very close to the normal level.” “Its gripping strength on the forefeet also recovered to up to 80 per cent.” Okano called the research project a major stride to pave the way for a similar medical technique to be used on humans.
