The advance, described online in the journal Cell Stem Cell, is the first time researchers have achieved &quot;therapeutic cloning&quot; of adults. Technically called somatic-cell nuclear transfer, therapeutic cloning means producing embryonic cells genetically identical to a donor, usually for the purpose of using those cells to treat disease. But nuclear transfer is also the first step in reproductive cloning, or producing a genetic duplicate of someone - a technique that has sparked controversy since the 1997 announcement that it was used to create Dolly, the clone of a ewe.</p><br clear="all"/>
