New Safety and Efficacy Evidence for Mitochondrial Donation Revealed

June 9, 2016

(Medical Xpress) – A new IVF-based technique is likely to lead to normal pregnancies and reduce the risk that babies born will have mitochondrial disease, according to researchers at the Wellcome Trust Centre for Mitochondrial Disease at Newcastle University. Published today in the journal Nature, scientists report the first in-depth analysis of human embryos created using a new technique designed to reduce the risk of mothers passing on mitochondrial disease to their children, which is debilitating and often life-limiting. The new technique, called “early pronuclear transfer”, involves transplanting the nuclear DNA from a fertilised egg into a donated egg, which contains healthy mitochondria, on the day of fertilisation.
