Canadian scientists have recently gone so far as to study cloned flies and have already achieved success. Scientists involved in the study claim that this fruit fly is the world’s first cloned insect. Walter Lauder, a professor at the University of Halifax and leader of the study, said that many people wonder why we want to clone flies first. This is because the kind of insect she hopes to clone can be easily tested further, and it is helpful for the perfection of other animal cloning processes, even human cloning. Or the technique can be used for the development of therapeutic stem cells. Previously, in the cloning, there were mature nuclei of genetic material that were injected into an egg that had been removed from its own nucleus. However, at that time, most of the cloned rats, sheep, and other animals died as soon as they were born. Scientists speculate that this is because adult genetic material cannot be properly replicated and thus cannot code for the correct growth of an embryo. If you use flies, it is relatively easy to knock out a functional gene in the flies. Therefore, if you try to clone a cell that knocks out a specific gene, you can test whether this gene is very important for the reproduction of genetic material. This is very important for scientists to reveal important genes involved in cell replication. If such genes can be identified, it is theoretically possible for a large number of successful mammalian cloning. Although scientists had previously tried to clone insects, it was the first time that according to Lauder, it was a success. During the cloning process, scientists have improved the traditional cloning procedure: they acquire nuclei from embryonic cells rather than extracting DNA from the nucleus of well-differentiated adult cells. They extract some nuclei from some developing fly embryos and then inject them into cultured fly eggs. Through more than 800 repeated experiments, they finally successfully cultivated five mature adult insects. This result has been published in the Journal of Genetics. Ken Rasham, a professor of mouse colony research at Temple University School of Medicine in Pennsylvania, pointed out that embryonic cells replicate more easily than adult cells. "However, it is not clear whether the mammal is also the case."
