Human fibroblasts cells from a Crigler-Najjar Syndrome (CNS) patient were used to generate integration-free induced pluripotent stem cells (iPSCs) by over-expressing episomal-based plasmids expressing OCT4, SOX2, NANOG, KLF4, c-MYC and LIN28. The derived CNS705-iPSC line is homozygous for the UGT1A1 c.877_890delTACATTAATGCTTCinsA mutation. Pluripotency was confirmed by the expression of associated markers and embryoid body-based differentiation into cell types from all three germ layers. Comparative transcriptome analysis of the iPSC and the human embryonic stem cell line H9 revealed a Pearson's correlation of 0.9468.
