China successfully cloned high quality Yellow Cattle

Introduction: the first high-quality Chinese Yellow Cattle successfully cloned by China Agricultural University was born on April 27, which marks that China has made important progress in the field of animal somatic cell cloning This is the news from the joint press conference of China bioengineering development center of the Ministry of science and technology and China Agricultural University According to Wang Hongguang, director of the China bioengineering development center, the nuclear donor cells used in the somatic cell cloning of the Chinese Yellow Cattle named "Powa" come from the ovary and ear skin tissue of a pure heifer of Jinan cattle less than six months old, while the oocytes used are taken from the ovaries of the cows slaughtered in the slaughterhouse According to the identification of relevant authorities, "pova" and its donor cell genetic material are exactly the same, but it is different from its surrogate mother Holstein cow in genetic origin According to the inquiry of the national science and Technology Literature Information Center of the Chinese Academy of Agricultural Sciences, this cloning is the first time in the world In addition, the success of cloning Chinese high-quality cattle made it possible to save the endangered cattle At present, Professor Li Ning's research group of China Agricultural University has carried out five batches of somatic cell cloning experiments, which has reached the international advanced level in technology According to Li Ning, since June this year, more than 20 somatic cloned cattle will be born in China Experts revealed that China will legislate for cloning technology China News Agency, Beijing, May 27, in the face of extensive debate at home and abroad on the application of cloning technology, China will issue regulations for the use of cloning technology in China Chen Zhangliang, President of Agricultural University of China, who participated in the research on the law, revealed this today According to reports, research on the legislation of cloning technology has begun, and research in Beijing and Shanghai has ended The main objects of the survey are people in the legal profession, ordinary citizens and social celebrities Chen said the results of the survey showed that the government is not allowed to use cloning technology in the field of human reproduction Among the scientists, one out of every 15 well-known scientists says the presence of clones should be banned, but it's hard to stop them Chen said scientists' curiosity about unknown fields will be the biggest obstacle to banning cloning from human reproduction In addition, he also revealed that the general Chinese people basically hold a negative attitude towards the idea that cloning technology is used for human reproduction, but in the case of family members' sudden accidents, few people firmly resist cloning At the same time, Chen Zhangliang also said that most people agree with the application of therapeutic cloning technology (author:) share to feed Weibo share to:
