Monkeys Cloned Using 'Dolly The Sheep' Technique


Share this article


Two monkeys have been cloned using the same technique that saw Dolly the Sheep cloned 20 years ago.

The genetically identical, long-tailed macaques, named Zhong Zhong and Hua Hua, were born in Shanghai.

They're the first primate clones made by Somatic Cell Nuclear Transfer (SCNT).

This saw researchers remove the nucleus from an egg cell and replace it with another nucleus from differentiated body cells.

The reconstructed egg then develops into a clone of whatever donated the replacement nucleus.

Researchers say this'll make it "a realistic possibility" for labs to conduct research with customisable populations of genetically uniform monkeys.

Although a primate has been cloned before, Zhong Zhong and Hua Hua are the first using SCNT.
