Cloned bunnies for Easter
Just in time for Easter, French scientists say they have successfully cloned rabbets from adult cells for the first time
A research team from France’s National Institute for Agricultural Research outside Paris made the breakthrough, which follows the successful cloning of sheep, cattle, goats, mice, pigs and cats elsewhere.
Scientists say cloning animals will help their understanding of human diseases by allowing them to target individual genes.
Cloned rabbits are particularly useful because their physiology matches humans more closely than rats or mice.
“Cloning might seem rather redundant in view of the bunny’s ability to reproduce by natural methods,” said a report of the research published by New York-baked Nature Biotechnology magazine.
But “the possibility of targeting specific genes during the cloning process could markedly enhance the use of rabbits as models of human disease,” it added.
The team used the usual cloning method of injecting cells from an about rabbit into an egg.
Jean –Paul Renard and his colleagues at the national institute said the discovery showed in theory any mammal could be cloned, as long as scientists adapted their methods to the physiological features of the egg and embryo.
Unlike the first cloned mammal Dolly the sheep, or the first cloned cat cc, the rabbits were not given names.
A US study published last month stoked debate over whether cloning is safe, or even if it produce exact copies when it showed cloned mice be came obese even when they did not overeat.
