| Research Abstract |
iPS cells were successfully generated from patients with the mtDNA A3243G mutation(Mt-iPS).The Mt-iPS cells exhibited a bimodal degree of mutation heteroplasmy. The mutation frequencies decreased to an undetectable level in six of 14 clones, while the others showed several-fold increases in mutation frequencies compared with those in the original fibroblasts. During serial cell culture passage and after differentiation, no recurrence of the mutation or no significant changes in the levels of heteroplasmy were seen. Mutation-rich, stable Mt-iPS cells may be a suitable source of cell for human mitochondrial disease modelling in vitro. Mutation-free iPS cells could provide an unlimited, disease free supply of cells for autologous transplantation therapy.
