Researchers will modify genes of left over embryos from IVF institutes. Researchers will receive a fertilized egg and they will go on with genetic modification by eliminating specific genes. They will monitor the development of the egg for one week and then they will destroy it. They hope they will manage in this way to decipher the gene mechanisms that transform a "fresh" fertilized egg in a healthy fetus. "Although research on mice and other animals have helped scientists to learn much about the development of embryos however it is necessary to make studies with human embryos to elucidate the development of the early stages," say the members of the research team.
Pros and Cons
This research has provoked positive and negative reactions. "This is an important step in fundamental level of scientific research. Recurrent miscarriage affects a very large number of people and the problem has not been investigated in depth. When this happens a miscarriage doctors usually say to couples simply try again. It is very important to increase our knowledge on this problem ", says Sarah Norcross, member of the organization Progress Educational Trust which helps people who face fertility problems and genetic diseases." We are against any form of research involving the destruction of human embryos” said the representative of the organization Comment on Reproductive Ethics.
