Genetic Drift Can Compromise Mitochondrial Replacement by Nuclear Transfer in Human Oocytes – Researchers show that using human mitochondrial replacement stem cell lines, even though the low levels of heteroplasmy introduced into human oocytes by mitochondrial carryover during nuclear transfer often vanish, they can sometimes instead result in mtDNA genotypic drift and reversion to the original genotype.
