US Genetic Storage and Cloning Company announced on the 5th that the company successfully cloned two cats using cloning technology. According to local media reports, the two kittens, named Tabriz and Baba Ginzo, were bred and bred respectively. They were born in the United States in June this year and are in good condition. It is reported that the US “Genetic Storage and Cloning†company uses chromatin transfer technology for this cloned cat. This technology is more safe and effective than traditional cloning technology, and the similarity between cloned animals and gene suppliers is high. The world's first cloned cat was bred by scientists from Texas A&M University in the United States and made a public appearance in 2002. Since the fur color of cats is not only related to genes, the first cloned cat is not completely similar to its genetic mother. The traditional cloning process involves first extracting the nucleus containing the genetic material, then implanting it in another egg cell with the nucleus removed, merging the two using micro-current stimulation, etc., and then promoting new cell division and reproduction to develop into an embryo. After the embryo has developed to a certain degree, it is implanted in the uterus of the animal to make the animal pregnant, and the animal having the same gene as the one providing the nucleus is produced. The success rate of this technique is very low. In most cases, the egg cells will die, or cloned into a deformed animal. However, the new technology used by the "Genetic Storage and Cloning" company is transplanted with chromatin. The researchers first removed the outer nucleus of the cell nucleus, then removed some of the regulatory proteins in the nucleus of the cell nucleus and the proteins around the chromosomes, and finally implanted the remainder in enucleated egg cells. The purpose of this technique is to make cloned embryos more like normal embryos. Some experts believe that non-genetic factors such as the maternal uterus environment can affect the fur color and temperament of cloned animals. Regarding the question of whether cloned animals resemble their gene providers, the company said in a statement that the two cloned kittens are an answer. He also pointed out that if the cloning process is carried out by highly trained researchers using cutting-edge technology, then cloned animals and their gene providers will be similar to the "incredible degree." According to a statement issued by the company, the company’s report on cloning cats has not submitted any traditional scientific tests, nor has it been verified by clone experts. Because it is not interested in the scientific problems of cloning and the medical prospects, it is only interested in the business opportunities of cloned pets. At present, the company plans to clone 5 pets for customers this year. The asking price is 50,000 US dollars each.
