China successfully cloned two endangered Xizang cattle breeds, Zhangmu and Apeijiaza, using somatic cell cloning technology in Chongqing Municipality.

China has successfully cloned two endangered cattle breeds, Zhangmu cattle and Apeijiaza cattle, found in the Xizang Autonomous Region. This is the world's first successful cloning of cattle from Xizang. Four male calves of each breed were recently born in Yunyang County, Chongqing Municipality. The scientists behind the breakthrough used somatic cell cloning technology, collecting ear tissue from the cattle and establishing a fibroblast cell line before using nuclear transfer technology to create clones embryos.
