Researchers in Japan Clone 8 Calves

WASHINGTON — Japanese researchers report that they have cloned eight genetically identical calves using cells removed from one adult cow.
In a study to be published this week in the journal Science, the researchers report that the calves were cloned with techniques similar to those used to clone the famed Scottish sheep known as Dolly.
The Japanese said they transferred the nuclei from cells removed from an adult animal into cow eggs from which the nuclei had been removed. The eggs and the transferred cell nuclei grew into blastocysts, which were placed into five unrelated cows.
