Abstract
Induced pluripotent stem cells (iPSCs) can be differentiated in vitro and in vivo to all cardiovascular lineages and are therefore a promising cell source for cardiac regenerative therapy. However, iPSC lines do not all differentiate into cardiomyocytes (CMs) with the same efficiency. Here, we show that telomerase-competent iPSCs with relatively long telomeres and high expression of the shelterin-complex protein TRF1 (iPSChighT ) differentiate sooner and more efficiently into CMs than those with relatively short telomeres and low TRF1 expression (iPSClowT ). Ascorbic acid, an enhancer of cardiomyocyte differentiation, further increases the cardiomyocyte yield from iPSChighT but does not rescue the cardiomyogenic potential of iPSClowT . Interestingly, although iPSCslowT differentiate very poorly to the mesoderm and endoderm lineages, they differentiate very efficiently to the ectoderm lineage, indicating that cell fate can be determined by in vitro selection of iPSCs with different telomere content. Our findings highlight the importance of selecting iPSCs with ample telomere reserves in order to generate high numbers of CMs in a fast, reliable, and efficient way. Stem Cells 2017;35:362-373.

Abstract
Human mitochondrial DNA (mtDNA) shows extensive within population sequence variability. Many studies suggest that mtDNA variants may be associated with ageing or diseases, although mechanistic evidence at the molecular level is lacking. Mitochondrial replacement has the potential to prevent transmission of disease-causing oocyte mtDNA. However, extension of this technology requires a comprehensive understanding of the physiological relevance of mtDNA sequence variability and its match with the nuclear-encoded mitochondrial genes. Studies in conplastic animals allow comparison of individuals with the same nuclear genome but different mtDNA variants, and have provided both supporting and refuting evidence that mtDNA variation influences organismal physiology. However, most of these studies did not confirm the conplastic status, focused on younger animals, and did not investigate the full range of physiological and phenotypic variability likely to be influenced by mitochondria. Here we systematically characterized conplastic mice throughout their lifespan using transcriptomic, proteomic,metabolomic, biochemical, physiological and phenotyping studies. We show that mtDNA haplotype profoundly influences mitochondrial proteostasis and reactive oxygen species generation,insulin signalling, obesity, and ageing parameters including telomere shortening and mitochondrial dysfunction, resulting in profound differences in health longevity between conplastic strains.
