Embryo created from Three Parents

A group of British scientists claims that they have created human embryos containing DNA from two women and a man. They created the embryos following a special procedure, that aims to create healthy embryos for couples to avoid passing on genes carrying diseases. So, they hopes that this procedure may help in future reasearch to produce embryos free of deadly inherited diseases.

"We are not trying to alter genes, we're just trying to swap a small proportion of the bad ones for some good ones," said Patrick Chinnery, a professor of neurogenetics at Newcastle University involved in the research.

In their research, Chinnery and colleagues used normal embryos created from one man and one woman that had defective mitochondria in the woman's egg. They then transplanted that embryo into an emptied egg donated from a second woman who had healthy mitochondria.

"If successful, this research could give families who might otherwise have a bleak future a chance to avoid some very grave diseases," said Francoise Shenfield, a fertility expert with the European Society of Human Reproduction and Embryology.

So, what is the future? It is too early to go forward. More tests are to be conducted to confirm the safety and efficacy of the process. Link
