Quantification of nucleic acid levels. DNA and RNA extracted from both pluripotent stem cell lines were quantified with a NanoDrop 2000 UV-Vis spectrophotometer (a) and with ethidium bromide staining on agarose gel electrophoresis (b). Error bars indicate mean ± SEM. Statistical comparison between hiPSCs and hESCs by paired Student’s t test (*p < 0.05). hESC human embryonic stem cell, hiPSC human induced pluripotent stem cell
