Early structural alterations in mitochondria in adult dopamine neurons induced by conditional ablation of MFN2

The human induced pluripotent stem cell (iPSC) line ZJUCHi002-A was established from renal epithelial cells present in urine (urinary cells) collected from an 8-year-old Charcot-Marie-Tooth disease type 2A (CMT2A) patient carrying point mutation in MFN2 (c.752C > T). Urinary cells were reprogrammed by retrovirus vectors containing reprogramming factors: OCT4, SOX2, KLF4 and c-MYC. The pluripotency, capacity of differentiation into 3 germ layers, silence of reprogramming factors and normal karyotype were all confirmed in this study.
