During the conference, whose organizers included to Jennifer Doudna, one of Crispr technology inventors, Dr. He spoke carefully about something fellow attendees considered & # 39; fullest within the ethically approved research, said one of the attendees, Dr. Fyodor Urnov, deputy director & # 39; the Altius Institute for Biomedical Sciences and visiting researcher at the Genomic Institute of Innovative University & # 39; California, Berkeley.
"If you heard his speech, is this cautious step, thoughtful and step by step", said Dr. Urnov. "He presented editing embryo & # 39; CCR₅. He was presenting the lecture their peers, professional Gene editors who know the field is advancing rapidly, so frankly the atmosphere in the room was, not want to say ho-hum, but it was "Yeah, sure, 've built over a decade & # 39; advances."
"What we now know is that while he was speaking, there was a woman in China carrying twins," said Dr. Urnov. "He had the opportunity to say" Oh and by the way, I'll come and ngħidilha, people, a woman carrying twins. "
He was not. "I have never poker against Dr. He", said Dr. Urnov.
Richard Hynes, a cancer researcher at the Institute of Technology & # 39; Massachusetts, who coordinated advisory group on human gene editing for the National Academy of Sciences and the National Medicine Academy, said similar group and organization in Britain were determined that if human genes have been edited, the procedure should only be done to address "serious unmet needs in medical treatment, should be well monitored, should be carefully followed, there should be full -kunsens ".
It is not clear why changing the gene to make people resistant to H.I.V. is "a serious unmet need." B Men & # 39; HI.V. avoid infecting embryos. Their semen containing the virus that causes AIDS, can & # 39; infecting women, but the virus can & # 39; washed their sperm prior to insemination. Or a doctor can & # 39; sperm injected into one egg. In both cases, the woman will not be infected and neither babies do not have.
Dr. He earned his Ph.D., from the University of Rice, in physics and his postdoctoral training at Stanford, was not & # 39; Stephen Quake, professor of bio-engineering and applied physics to work on DNA -sekwenzar, without jeditjah.
