Characterization of mtDNA in A01 MELAS-iPSCs. (A) Genetic analysis of A01 fibroblasts and MELAS-iPSCs at passage 5 by Sanger sequencing. Arrows indicate m.13513 position. (B) RFLP analysis of A01 fibroblasts and MELAS-iPSCs. The 120 bp and 93 bp + 27 bp fragments indicate the presence of mutant and wild-type mtDNA, respectively. Heteroplasmy level of m.13513G>A mtDNA (C) analyzed by ARMS-qPCR and mtDNA copy number (D) in A01 fibroblasts and MELAS-iPSCs. MELAS-iPSCs were collected at the following passage numbers: #15 at p5 and p20; #58 at p5 and p20; #30 at p5, p12, p20, p31 and p43; #67 at p5, p12, p21, p33 and p45.
