…researchers led by Dr Dieter Egli, of the New York Stem Cell Foundation, discovered that when the nucleus is transferred some of the defective mitochondria can go with it, according to a paper in the journal Cell Stem Cell.
But other scientists said that overall the findings of the study were actually grounds for “optimism” as this was a relatively uncommon occurrence.
In the study, the researchers found that half the cell lines created from using the nucleus and donor egg contained a low percentage of mitochondrial DNA from the original egg cell.
In some cases, this original mitochondrial DNA disappeared over a period of six months, but in others it took over the donor cell so that 100 per cent of the mitochondrial DNA matched that of the transferred DNA.
