Relative gene expression levels of Oct4, Sox2, and Nanog in human fibroblasts, keratinocytes, CD133⁺ cells from cord blood, and NSCs. The relative gene expression levels in fibroblasts, keratinocytes, and CD133⁺ cells compared with hESCs were calculated from the data reported by Giorgetti et al.⁸⁵ and Page et al.⁸⁶ The relative gene expression levels in human NSCs compared with hESCs were used from the data reported by Kim et al.¹³
