中国利用体细胞克隆技术在重庆成功克隆了樟木和阿沛加杂两个濒危藏牛品种。 China successfully cloned two endangered Xizang cattle breeds, Zhangmu and Apeijiaza, using somatic cell cloning technology in Chongqing Municipality.

中国已成功克隆了西藏自治区发现的两种濒临灭绝的牛品种——樟木牛和阿沛家杂牛。 China has successfully cloned two endangered cattle breeds, Zhangmu cattle and Apeijiaza cattle, found in the Xizang Autonomous Region. 这是世界上首次成功克隆来自西藏的牛。 This is the world's first successful cloning of cattle from Xizang. 近日，重庆市云阳县各品种产下4头雄性小牛。 Four male calves of each breed were recently born in Yunyang County, Chongqing Municipality. 这一突破背后的科学家们使用了体细胞克隆技术，从牛身上收集耳组织并建立成纤维细胞系，然后使用核移植技术创建克隆胚胎。 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.
