World's first cloned rabbit has survived for 5 months

The world's first cloned rabbit, produced with the body cells of an embryonic rabbit, passed a molecular biology test, on July 10, at the Chinese Academy of Agricultural Sciences. Born on February 12, 2007, the cloned rabbit has survived for 5 months.

The cloning experiment, conducted by Li Shangang, a PhD at the National Center for Molecular Genetics and Breeding of Animals at the Institute of Veterinary Sciences, selected the posterior skin cells of a 20-day old rabbit embryo.

After acquiring the fibroblast cell, Li used this type of cell as the donor cell; and injected it into a rabbit's oocyte that had been applied by a nucleation method with electric devices. Finally, the scientist transferred the modified cell into the parent rabbit's fallopian tube.
