For the first time, human embryonic DNA has been successfully modified by Chinese scientists. Western biologists have voiced serious moral concerns about this - the South China Morning Post reported.

Human embryo

Huang Chen-chiu, a professor at Sun Yat-sen University in Guangdong, was "eliminating" a delicate genome responsible for the beta thalassemia, using transparent technology. Beta thalassemia is the most common, sometimes fatal, blood cancer of South Chinese children. Their study was published in two of the most prestigious scientific journals, British Nature and American Science, and Ethics.
In the Protein and Cell magazine, the Chinese scholars understand that they are conducting such research in a moral debate.
For the study, they used "problematic embryos discarded by hospitals" or used more sperm-fertilized ova, which "scientific worlds have been using for decades because they could never be used."
British biologist Edward Lanphier told Nature that this research should be paused until there is a broad debate about what kind of agency he is pursuing.
Although Huang did not comment on the reactions, according to, his work found strong support among Chinese biologists. According to Chen Kuo-chiang, a professor of biology at Cinghua University, the critics are delusional: "If we do what they say, human embryos would not be able to be researched at all. the key to health, youth, longevity is the redesign of human gays. All of this will be possible in the future and will free many from suffering. "
Chao Si-min, a biologist at Fudan University in Shanghai, does not find Huang's research morally unacceptable because "only embryos are tested" and "research is far from clinical use".
According to Chao, human genetic modification is "inevitable", technology is used on plants and animals, and the next step is man. He warned, however, that - like all mбs eljбrбsnak - this also has its korlбtai йs kockбzatai. "The gйnszekvenciбk megvбltoztatбsa cause vбratlan problйmбkat that цrцklхdnйnek йs tovбbbi kбrosodбsokat, betegsйgeket vбltanбnak out aztбn nemzedйkrхl nemzedйkre, tehбt kцzцtt laboratуriumi frames should be хket szigorъan the human race would be extinct if we massively altered DNA uncontrollably. "
Huang's research team carried out experiments on 86 "destroying" embryos, and only 28, or about 30 percent, were successful in genomic transfer. Another worrying phenomenon was encountered: Genetic Exploitation Technology (CRISPR) often loses the selected gene, and after treatment there were mutations in the embryo.
The South China Morning Post commented on the experiments and their response that this is not the first time Asian scientists have conducted experiments on human embryos and this has provoked disgust in the West. A dozen years ago, South Korean scientists announced that they had succeeded in cloning embryos. They nationally celebrated them until it was revealed that they were not telling the truth.
According to a new study, Asian researchers are generally more likely to experiment with human embryos than their Western counterparts, because the public is more likely to accept it and less religious objection.
