It is a technique called nuclear transfer -- the same used to create Dolly the sheep -- and until Mitalipov's research there had been skepticism over whether a primate could be cloned in the same manner.
The problem is that making them using somatic-cell nuclear transfer involves breaking up viable embryos, since the cells in question are found inside early-stage embryos, called blastocysts.
