HONG KONG (AP) – Chinese researcher
He said he had helped create the world's first babies, announced today that second pregnancy could develop.
Jiankui, a 34-year-old link teacher in the southern city of Shenzhen, revealed the possible pregnancy in his first public announcements for his controversial work at an international conference in Hong Kong.
He says he has changed DNA from
Two twins were born at the beginning of the month to try to make them an immune to the AIDS virus. The scientific community has condemned the experiment, and universities and government groups are investigating the situation.
The second possible pregnancy is in a very early stage and more time is required to confirm which will continue, he says.
After Talking, leading scientists said that there are still more reasons to be worried now and more questions than answers. The conference director described the experiment as "irresponsible", stating that it was proof that the scientific community had failed to self-regulate and avoid the first attempts to change DNA.
Changing DNA before or at the moment is a concept is a highly controversial issue because it can inherit the changes and could harm other genes. This practice is prohibited in some countries, including the United States, except for laboratory research.
I have defended her choice of HIV rather than fatal inherent disease to try genetic editing, and insist that women could benefit.
"This defense is needed because there is no vaccine available," said the researcher. But the scientists did not approve their approach.
"This is a truly unacceptable increase," said Jennifer Doudna, a scientist at the University of California-Berkeley and one of the CRISPR gene editing instrument inventors said she was using. "I'm grateful that she appears today, but I do not think we've heard the answers, we need to understand the stimulus for this."
Doudna is paid by the Howard Hughes Medical Foundation, which also supports the Associated Press Medicine and Science Department.
At present there is no independent confirmation of He's allegation, who has not yet published his research in any scientific period in which experts can prove that. At the conference, he refused to answer a number of questions, including who was paying for work, how he ensured that participants understood the potential risks and benefits and why he kept his work secretarily until he had complete it
The regulators prevented the damnation of the experiment as being unhealthy and uncertain.
China's National Health Commission ordered local officials in the Guangdong province to investigate the actions of Him and the center that works in the University of South Science and Technology is also studying what happened.
