Somatic copy-number mosaicism in human skin revealed by induced pluripotent stem cells

ABSTRACT: Reprogramming human somatic cells into induced pluripotent stem cells (iPSC) has been suspected of causing de novo copy number variations (CNVs). To explore this issue, we performed a whole-genome and transcriptome analysis of 20 human iPSC lines derived from primary skin fibroblasts of 7 individuals using next-generation sequencing. Prior to this CNV study, the human iPSC lines and one hES (H1) were characterized by a set of quality control criteria, including gene expression analyses by microarray. This analysis demonstrated uniform up-regulation of hESC-specific genes in all our hiPSC lines, while fibroblast specific genes were downregulated Total RNA obtained from iPSC lines and H1 line was submitted for microarray analysis using HumanHT-12 v4 BEADCHIP (Illumina).
