Recently, in the news, a Chinese researcher has just claimed to have created the world’s first two genetically modified twins with new tools. Ha Kien Khue, a researcher in Shenzhen City, Guangdong Province, is well known. He confirmed that embryonic adjustments of seven couples and one of them resulted in successful DNA adjustment.
Mr. Xia said that the goal of the experiment was not to treat or to prevent genetic diseases. But it is tried to incorporate biological features. It is that few have such as the ability to resist HIV infection.
According to Chinese scientists, the couples who participated in the experiment did not accept identity claims or interviews with the news. He refused to disclose that where is about of the couples.
He recruited volunteer couples from an AIDS rights group that is called Baihualin. Genetic modification is performed during artificial insemination (IVF). Scientists began to wash sperm of men to separate from semen where contains the HIV virus. After transplanting sperm and eggs to create embryos, genetic modifiers are added.
After 3-5 days, they removed some cells from the embryo and checked the progress of gene regulation. Couples are choose between embryonic or non-regulated embryos for pregnancy. “16/22 embryos were adjusted and 11 embryos were used in 6 attempts to attach to the uterus before a pair of twin pregnancies”, Mr. Xia said that.
Initial screening results revealed that one of the twins was inherited from both copies which are modified gene. There are no signs that other genes was compromised.
The scientist said he had informed the volunteers of the mortality target and reminded the trial of risks. In addition, he will support for artificial insemination which is completely free. He also pledged to provide insurance for all babies born in this experiment. He accepts medical support for children up to 18 years of age or more if they agreed.
