We know that in recent years, scientists have cloned mammals such as pigs, cows and sheep, but there is no way to clone primates such as monkeys. However, if we want to establish an animal model of human diseases, it is impossible without monkey cloning technology. Scientists in China made unremitting efforts and finally succeeded.
Under the joint research of Hebei Agricultural University and Biotechnology Research Center of Shandong Academy of Agricultural Sciences, Chinese scientists successfully cloned two white rabbits-Lu Xing and Lu Yue-through the experimental project of "Study on Isolation and Cloning Embryonic Stem Cells from Primitive Germ Cells of Livestock". This experiment shows that China has successfully mastered embryo cloning, although it has not reached the level of somatic cell cloning Dolly the sheep, but it has laid the foundation for the progress of cloning technology in China.
After that, the Institute of Animal Reproduction of Guangxi University in China successfully bred cloned rabbits which were larger than ordinary rabbits. Because rabbits are closer to human physiology, the successful birth of cloned rabbits is helpful to human medical research. 2. On May 27th, 2002, China Agricultural University, in cooperation with Beijing Genda Technology Co., Ltd. and Hebei Lutai Farm, successfully cloned the first high-quality yellow cattle in China-Red Jinan cattle. The somatic cloned cattle named "Bowa" has been identified by authoritative departments, and some cloning technical indicators have reached the international level. Jinan cattle is an excellent local yellow cattle breed unique to China, which is distributed in Hebei Province, China. Its main characteristics are cold tolerance and low fat. However, its number has dropped sharply and it is on the verge of extinction.
The successful cloning has a profound impact on the protection of endangered species in China?
After repeated efforts and summing up experience, Chinese scientists have made some small breakthroughs. We know that the technology of cloning nonhuman primates is blank all over the world, so the work that scientists need to do is even more arduous. Scientists in China overcame difficulties and finally bred two cloned monkeys. Their names are Zhong Zhong and Hua Hua.
