Cloning mice: For the first time, a donor mouse has been cloned using a drop of peripheral blood from its tail

Since Dolly the sheep in 1996, reproductive cloning has continued to advance; nearly 20 different mammalian species have now been cloned. Researchers have now developed a unique cloning procedure using peripheral blood cells, which may be collected repeatedly from a single animal and so facilitate preservation of infertile mouse strains.
