Chinese scientists have defended their work as genetically engineered for the first children of the world.
When speaking of the genome of the Hong Kong genome, Jianku said his work was "proud". "Gender-edited embryos" was another potential pregnancy at the beginning, he said.
Claims have not been independently verified. Many scientists have condemned the announcement, calling on some monster ideas.
This work is prohibited in most countries.
Prof. The University – at the Southern University of Science and Technology – said he had not heard the research project and started an investigation.
Prof, announced earlier this week, had double embryo DNA, twin girls, to prevent HIV hiring.
In the video, he has deleted a gene called CCR5 for HIV to be resistant to the virus.
His claims were highly criticized by other scientists, one of which was called "monstrous".
Hundreds of Chinese scientists also signed a letter condemning the investigation into social media, saying they were "completely" opposed.
"True, this experiment is monstrous. Genesis is an experimental edition and it is still not related to target mutations, after survival of genetic diseases, including cancer development," Prof. Julian Savulescu, an ethics expert at the Oxford University, told the BBC.
"This experiment shows normal healthy children the risks of editing genes without actual real benefits."
& # 39; Normal & healthy & # 39;
On Wednesday, he lectured at the Human Genome Editing Summit at the Hong Kong University for the first time since his work began.
The twin girls – known as "Lulu" and "Nana" – were "normal and healthier" and were planning to control twins in the next 18 years.
Eight couples, the liver parent and HIV are negative, voluntarily signed up for the experiment; He dropped a little later.
Initially, he financed his experiment.
Prof. He also said that the review was sent to the scientific journal, although it did not include the journal's name.

The use of the Crispr genre editing tool is not new to the scientific world, and was first discovered in 2012.
It works using "molecular scissors" to modify, either cutting, replacing or collapsing a very specific DNA tube.
Gene editions help prevent heritable diseases by eliminating or changing embryo coding removal.
But experts may worry about messing with an embryo genome, because of the individual who assumes these changes, but also for future generations.
Many countries, including the United Kingdom, have laws to prevent the use of embryonic genome to reproduce human beings.
Scientists can carry out genotyping studies on the IVF embryo, as long as they are destroyed to avoid becoming a baby.
