[] Message: Korea a life science research Institute recently announced that the Institute has been cloned from 11 may only be carrying human cells in rat pups. Currently, researchers are in young rats for genetic tests, you need at least 1 month's time to do the final confirmation.
According to science and technology daily reported that the researchers first from fertilization 4 days of experimental rat embryo splitting off the placenta, and then in the rest of the embryonic tissue into human embryonic stem cells. These stem cells is from the United States national institutes of health registration of human stem cell bank in, injection site before EGFP (GFP gene). Injection of stem cells from embryos after approximately 6 hours of vitro, reinsertion agent mouse of the uterus, the fertilized egg to bed. Researchers in 4 females mice implanted in utero respectively by 8-12 after processing of embryos.
Already born young rats 7 just born 6 January, the remaining 4 only 27, was born. The new-born infant rats undergoing genetic tests to determine their "blood ties".
Researchers said that this experiment is to study human embryonic stem cells in vivo conidia and further research on stem cells cultured in the best environment. Previous research has conducted some relate to the adult mice implanted into human stem cells, but having human stem cells of animals to be born will be the first time in the world.
The Institute believes that this test is very safe, born in experimental rats can neither with certain organs, mankind will not grow into half-human, half-rat Monster.
