Gene expression of CDH11, SPP1, and DMP1 Effect of 45s5 and 6P53-b GCM on MC3T3-E1 subclone 4 gene expression of (A) cadherin 11 (CDH11), (B) sialo phosphoprotein (SPP1), and (C) dentin matrix protein (DMP1) relative to control treatments. Data presented represent the means ± S.D. of triplicate experiments. Significant differences between treatments were determined by One-Way ANOVA with Dunnett posttest comparison. *p < 0.05, **p < 0.01, ***p < 0.005 compared to control.
