British researchers have developed an embryo from the DNA of two women and one man. They hope the procedure will lead to the creation of embryos free of inherited diseases.

30-Second Summary

The researchers used embryos created from the egg of one woman and the sperm of one man.

They then removed the defective mitochondria, the parts of a cell that produce energy, from the woman’s egg. They replaced these with the healthy mitochondria from a second woman cells.

Scientists hope that this research can help them create embryos that are free of inherited diseases.

Researchers commented that the embryo is still fundamentally the product of two parents, because the nucleus of the egg is left alone in the process.

"Most of the genes that make you who you are are inside the nucleus," Professor and researcher Patrick Chinnery said. "We're not going anywhere near that."

Scientists have thus far created 10 embryos using the procedure, but they have not been allowed to develop past five days.
