Using the technique that created Dolly the sheep, researchers from the RIKEN Center for Developmental Biology in Kobe, Japan, have identified a way to produce healthy mouse clones that live a normal lifespan and can be sequentially cloned indefinitely. In an experiment that started in 2005, the team led by Dr. Teruhiko Wakayama has used a technique called somatic cell nuclear transfer (SNCT) to produce 581 clones of one original "donor" mouse through 25 consecutive rounds of cloning.
