Expression of undifferentiation (a) and osteogenic marker (b) genes standardized by TBP in iPSCs during osteogenic differentiation. The values are represented as the mean ± S.D. from two-six independent samples. One-way analysis of variance (ANOVA) with Bonferroni correction for multiple comparisons was applied. *P < 0.05, **P < 0.01 versus day 0.
