Effects of iRoot SP on osteogenic differentiation in hSCAPs. A Relative expression levels of the osteogenic genes OCN, OSX, Runx2, and DSPP in hSCAPs normalized to the housekeeping gene GAPDH. B Western blot results showing the upregulated protein levels of osteogenic markers in the 0.2 mg/mL iRoot SP group. GAPDH was used as a loading control. C Grayscale analyses of the results shown in (B). *P < 0.05, **P < 0.01, and ***P < 0.005. Error bars: mean ± standard deviation
