Implanted virus recombinant gene Han cloned cat body fluorescence

even in the dark, the cat's eyes still shineNow South Korean scientists have cloned kittens that glow in the dark, not just in the eyesSuch cloned cats not only bring new pleasure to pet fans, but also promise to overcome the genetic
disease sedative diseases in humansImplanted virus recombinant genesthe Korea Times reported on the 13th, South Korea's Gyeongsang National University, scientists under the leadership of Professor Kong Ai-gen carried out the studyThey first removed the epidermal cells of an adult female Turkish Angolan cat, processed them and transplanted them into the female cat's egg to remove the nucleus, and implanted a virus in the egg to change the genetic composition of the epidermal cellEventually, the eggs are transferred to the female cat's uterusBetween January and February this year, they received four kittens by caesarean section, one of which died at birth, and the rest are nowhealthy, Kong saidThe three white kittens were born weighing between 110grams and 136 grams and are currently weighing about 3.5 kgOn the face of it, these cats are no different from ordinary pet cats, but as long as they are in the dark, their "abnormalities" will appear12 in Qingshan Nandao Jinzhou Qingshan National University laboratory, scientists put cloned cats and ordinary cats under ultraviolet radiationAs a result, the average cat reflects normal green light, while the cloned cat emits a faint red fluorescenceThe scientists explained that the implanted virus successfully altered the genes of the "fertilized egg" cells
, making the kitten's skin cells contain fluorescent proteins"We found fluorescent proteins in all the organs of the dead cat, which proves that we have effectively cloned genetically recombined cats, " Kong said"
beneficial geneticdiseasetreatment researchthe world's first cloned cat was born in 2002 at Texas University of Agriculture and Mechanical SciencesKong successfully cloned the cat for the first time in 2004Since then, he has led a government-funded project to clone animalsThe purpose of this project is to use the results of research to combat theof human suspectedSouth Korean researchers believe the new cloning technology could not only save endangered species such as tigers by cloning, but could also be used to combat theof human geneticdiseasesIn response to Kong's team's findings, a spokesman for the Ministry of Science and Technology of Korea said: "The production of genetically mutated cloned cats is of great significance because it can be used to treat genetic diseases, as well as to replicate and human specimens of animals with the same disease." "
predicts that once people can clone cats with the same disease as humans, they will greatly accelerate relevant therapeutic research and drug development, because scientists will be able to carry out clinical trials in cats Cats may have 250 genetic diseases common in humans, he said (Hu Xiaobai)
