UK scientists granted permission to genetically modify human embryos
An application from the Francis Crick Institute in London is approved by fertility authority.
The UK's fertility research regulator has approved an application by a laboratory for permission to genetically modify human embryos.
The Human Fertilisation and Embryology Authority (HFEA) approved an application from the Francis Crick Institute in London on Monday.
The move is the first time scientists in the UK have been given permission to genetically modify human embryos.
But they will not be able to implant the embryos into women for treatment.
A statement from HFEA said:
Dr Niakan's team want to study embryos as part of their research into what happens in the first seven days after fertilisation and as they investigate miscarriage.
Dr Niakan has said that in the future the research could lead to "tweaking" embryos used in IVF to maximise chances of survival.
HFEA approval means the new work could begin in the next few months.
