Abstrakt:	Human-derived experimental systems such as induced pluripotent stem cell (iPSC)-derived models are useful tools to study mechanisms and potential therapeutic approaches for mitochondrial disorders. Here, we generated two iPSC lines from fibroblasts of patients carrying mutations at MT-ATP6 (m.8993 T>G). One patient with 96 % heteroplasmy suffered from Neuropathy, Ataxia, and Retinitis pigmentosa (NARP) syndrome, while the other patient with a homoplasmic mutation suffered from Maternally Inherited Leigh Syndrome (MILS). For reprogramming, we delivered reprogramming factors using Sendai virus and evaluated the pluripotency characteristics of the derived iPSCs. The degree of heteroplasmy remained stable after reprogramming.
