[…] Since the birth of Dolly the sheep in 1996, researchers have cloned about 20 different species, including rabbits, goats, cows and cats. Yet they so far have been unable to create biologically identical copies of any monkey or primate, including humans, possibly because their reproductive biology is more complicated.
But the refinements described in the latest experiment suggest that “it’s a matter of time before they produce a cloned monkey,” said Jose Cibelli, a cloning expert at Michigan State University, who wasn’t involved in the study. It also means, he added, “that they are one step closer to where the efficiency is high enough that someone is willing to try” to clone a person, though that remains a distant—and disturbing—prospect.
The experiment was published online Wednesday in the journal Cell. It was funded by Oregon Health and Science University and a grant from Leducq Foundation of France.
