The conversion of lineage-committed cells to induced pluripotent stem cells (iPSCs) by reprogramming is accompanied by a global remodeling of the epigenome, resulting in altered patterns of gene expression. Here we characterize the transcriptional reorganization of large intergenic non-coding RNAs (lincRNAs) that occurs upon derivation of human iPSCs and identify numerous lincRNAs whose expression is linked to pluripotency. Among these, we defined ten lincRNAs whose expression was elevated in iP ...[more]

Project description:Human pluripotent stem cells hold great potential for regenerative medicine, but available cell types have important limitations. While embryonic stem cells derived from fertilized embryos (IVF-ESCs) are considered the "gold standard" of pluripotency, they are allogeneic to potential recipients. Autologous induced pluripotent stem cells (iPSCs) are prone to epigenetic and transcriptional aberrations. To determine whether accumulation of such aberrations is intrinsic to somatic cell reprogramming or secondary to the reprogramming method, we generated a genetically matched collection of human IVF-ESCs, iPSCs, and ESCs derived by somatic cell nuclear transfer (SCNT; NT-ESCs), and subjected them to genome-wide genetic, epigenetic and transcriptional analyses. SCNT-based reprogramming is mediated by the full complement of oocyte cytoplasmic factors, thus closely recapitulating early embryogenesis. NT-ESCs and iPSCs derived from the same somatic donor cells contained comparable numbers of de novo copy number variations (CNVs), suggesting that the two reprogramming methods may not differ significantly in mutagenic or selective pressure. On the other hand, the DNA methylation and transcriptome profiles of NT-ESCs corresponded very closely to those of IVF-ESCs, while iPSCs differed markedly from IVF-ESCs and harbored residual DNA methylation patterns typical of parental fibroblasts, suggesting incomplete reprogramming. We conclude that human somatic cells can be faithfully reprogrammed to pluripotency by SCNT and are therefore ideal candidates for cell replacement therapies. 16 matched samples, two IVF-ESCs, five sendai produced iPSC lines, two retro-virus produced iPSC lines, four NT-ESCs, the parental fibroblast line, and the sperm and oocyte donor were genotyped using the Illumina Omni5, which interrogates 4.3 million SNPs across the human genome. Additionally, matched samples from a patient with Leigh syndrome, a NT-ESC line, three iPSC lines, and the parental fibroblast line were genotyped using the Illumina Omni5.
