'Human-animal' embryo green light | |
(about 2 hours later) | |
Regulators have agreed in principle to allow human-animal embryos to be created and used for research. | |
But scientists wanting to use hybrids will still need to make individual applications, the Human Fertilisation and Embryology Authority said. | |
An HFEA consultation showed the public were "at ease" with the idea when told it could pave the way for therapies for conditions such as Alzheimer's disease. | An HFEA consultation showed the public were "at ease" with the idea when told it could pave the way for therapies for conditions such as Alzheimer's disease. |
Opponents have said many people would be "horrified" by such a move. | |

WHAT HAPPENS ELSEWHERE? Australia - Embryos allowed to be created for research, but human-animal hybrids banned. The only exception is to test the quality of spermCanada - Legislation bans the creation of human-animal embryosUS - Federal funds can only be used for research involving pre-existing embryos - such as those left over from fertility treatment - and there is a ban on hybrid embryosElsewhere - Other countries do not specifically legislate on hybrid embryos. But Italy and Germany only allow the use of pre-existing embryos and many others including Austria, Norway and Tunisia do not allow embryo research at all | WHAT HAPPENS ELSEWHERE?

Scientists want to create hybrid embryos by merging human cells with animal eggs in a bid to extract stem cells. The embryos would then be destroyed within 14 days. | |
The cells form the basic building blocks of the body and have the potential to become any tissue, making them essential for research. | The cells form the basic building blocks of the body and have the potential to become any tissue, making them essential for research. |
At the moment, scientists have to rely on human eggs left over from fertility treatment, but they are in short supply and are not always good quality. | At the moment, scientists have to rely on human eggs left over from fertility treatment, but they are in short supply and are not always good quality. |
Two teams from Kings College London and Newcastle University have already applied to the HFEA to use hybrid embryos. | Two teams from Kings College London and Newcastle University have already applied to the HFEA to use hybrid embryos. |
It is now expected individual hearings for these two applications will be held in November with other scientists expected to follow suit. | |

Dr Lyle Armstrong, of Newcastle University, said: "It does seem a little abhorrent at first analysis, but you have to understand we are using very, very little information from the cow in order to do this reprogramming idea. | |
"It's not our intention to create any bizarre cow-human hybrid, we want to use those cells to understand how to make human stem cells better." | |

The HFEA decision comes amid government moves to lay down regulations covering such research - the law governing embryo research is out of date and does not cover the issue. | The HFEA decision comes amid government moves to lay down regulations covering such research - the law governing embryo research is out of date and does not cover the issue. |
The government originally proposed banning the technique in a White Paper, but reversed its decision this year in a bill which indicated ministers were minded to allow hybrid embryos which were 99.9% human and 0.1% animal, following a backlash by scientists and patient groups. | The government originally proposed banning the technique in a White Paper, but reversed its decision this year in a bill which indicated ministers were minded to allow hybrid embryos which were 99.9% human and 0.1% animal, following a backlash by scientists and patient groups. |

The regulator can grant licences to scientists to pursue such research, but will have to change its criteria if future rules contradicted its own practices. | |
