Perspectives

CLONING:
Pigs Is Pigs

Randall S. Prather

Since the first report of a cloned animal (Dolly the sheep) 3 years ago, cloning mammals has become something of a cottage industry. As Prather discusses in his Perspective, pigs can now be added to the august list of cloned animals, which includes cows, goats, and mice. This is a particularly spectacular achievement because pig cloning has turned out to be notoriously difficult. The pig is also a valuable domestic animal to have cloned because, being physiologically close to humans, its organs can be used in xenotransplantation.
