In 1986, British scientists Weila Anderson cloned a sheep with embryo cells,others have since cloned cattle, mice, rabbits, monkeys and other animals.All of this cloned animals successed by using embryonic cells as donor cells for nuclear transfer.This clone technology is easier and more suitable for research.
But Cloned sheep "Dolly" is burned by using Mammary epithelial cells (somatic cell) as the donor cells for nuclear transferred,It opened a new chapter in the history of biological cloning, breakthrough the traditional use of embryonic cells for nuclear transfer and has made significant progress in the cloning technology.Dolly fully inherited all DNA's genetic characteristics of its biological mother-Somatic cell provider-Dorset ewes,is the hundred percent of the "copy" of the Dorset ewes.
