About the Consultation

The HFEA recently held a consultation on the ethical and social implications of creating human/animal embryos in research.

Hybrids and Chimeras Consultation document

Hybrids and Chimeras (888 Kb)
Researchers around the world are using stem cells from human embryos in research to develop their understanding of a number of different diseases. Many scientists now believe that embryonic stem cells may also, in future, lead to new therapies.

In November 2006, the HFEA received applications from two different research teams for a licence to derive stem cells from human embryos, created from animal eggs instead of human eggs.

If this research is permitted, it will be the first time that scientists in the UK have created embryos in a research project which contain both human and animal DNA.

This consultation aims to explore public opinion on the broad range of hybrid and chimera research.

Since the consultation document was printed, the House of Commons Science and Technology Committee has published the report of its inquiry into hybrid and chimera research. Read more about their inquiry and report.

Public dialogue

During May twelve deliberative groups were held across the UK to help the HFEA to explore and understand public perceptions, motivations and attitudes to hybrid research. Half the participants of these groups were subsequently invited to attend a day long event, held in the first week of June. A short video this event can be viewed below:

In early July, an opinion poll will be carried out to further explore public opinion on this issue.

Public event

On Tuesday 26th June the HFEA held a public event to discuss the issues raised through the Hybrids and Chimeras consultation.

The event was chaired by TV's Nick Ross and a panel made up of:

Dr Lyle Armstrong - Lecturer in Stem Cell biology, University of Newcastle
Rev. Dr. Stephen Bellamy - Vicar of St. James' church Birkdale, Southport
Josephine Quintavalle - Co-founder of Comment on Reproductive Ethics (CORE)
Christine Young - Special Parkinson's Research Interest Group
John Cornwell - Director of the Science and Human Dimension Project at Jesus College, Cambridge and regular writer for The Tablet

The discussion was wide and varied with a mix of questions from the floor and polling questions.

Some of the key issues raised were;

Whether or not the research is necessary given therapeutic advances made in stem cell research to date have been from adult and cord blood stem cells.
The notion of boundaries in science and whether or not this type of research crosses a boundary in the species divide.
The efficacy of the proposed research, exploring if it is indeed possible, and if so how applicable research findings from hybrid embryos would be to human beings.
The use of potential treatments when animals have been used in their production or research.
Whether or not the moral and ethical reasons not to pursue the research outweigh the potential benefits it might bring.
