Science Fiction Network, July 9 (She Xiaoyu) According to the National Institute of Diabetes, Digestive and Kidney Diseases, nearly 70% of the world's people suffer from some form of lactose intolerance. Among them, the proportion of Lactose intolerant people in Asia is the highest, reaching more than 90%.
Recently, according to foreign media reports, Russian scientists have successfully bred a new breed of genetically modified cows that can produce lactose-free milk.
Professor Petr Sergiev of the Skoltech Institute in Moscow says their ultimate goal is for cows to produce naturally low-allergy milk varieties. They need to go through constant exploration and experimentation, spending a lot of time and money.
Professor Petr Sergiev suggested that having cows produce lactose-free milk is "a necessity for future agriculture" and a cool project.
The Federal Centre for Animal Sciences in Ernst, in collaboration with the Skoltech Institute and Moscow State University, "knocked out" the gene responsible for β-lactoglobulin, which is responsible for "lactose malabsorption" in humans. They managed to clone her using somatic nuclear transplantation (SCNT), transferring the nuclei of regular cells from donors to an egg with the nucleus removed. The resulting embryos are then implanted into the cow's uterus and performed for full term.
The metabase calf was reportedly born in April 2020 and weighed about 140 pounds at birth.
It has been with the rest of the institute's cows since May, and its adaptation process has been very fast, and now it weighs nearly half a ton, is in good health, and has a normal reproductive cycle.
Technology is constantly evolving, and the future of lactose-free milk will bring a beautiful gospel to lactose intolerants!
