“This research shows us what’s possible,” Wei Li, a senior author of the study1, said in a statement. Li conducted the work with colleagues at the Chinese Academy of Sciences. But for now, the notion of reproducing the experiment in humans is more a matter of science fiction than science. The new study, which appeared in Cell Stem Cell, does not indicate that researchers can now or could anytime soon pull off a similar feat with people.
“It really opens your imagination for what you can do in mammals,” said Dr. Nissim Benvenisty, the director of the Azrieli Center for Stem Cells and Genetic Research at the Hebrew University of Jerusalem, who was not involved in the study.
