Figure Lengend Snippet: Knockdown of enhancer of zeste homolog 2 inhibits steo/dentinogenic differentiation potential of human apical papillary stem cells. A: Quantitative polymerase chain reaction showed that the expression of enhancer of zeste homolog 2 (EZH2) was inhibited in human apical papillary stem cells (hSCAPs); B: Western blot analysis confirmed the knockdown of EZH2 in hSCAPs; C: Knockdown of EZH2 decreased alkaline phosphatase activity in hSCAPs; D and E: Alizarin red staining and quantitative calcium analysis demonstrated that knockdown of EZH2 inhibited mineralization in hSCAPs; F-H: Quantitative polymerase chain reaction showed that knockdown of EZH2 downregulated mRNA expression levels of bone sialoprotein (F), dentin sialophosphoprotein (G), and osteocalcin (H) in hSCAPs. GAPDH and ACTB was used as the internal controls. Data are presented as the mean ± SD ( n = 3). Statistical analysis was performed using Student’s t -test. a P ≤ 0.05, b P ≤ 0.01, c P ≤ 0.001. EZH2: Enhancer of zeste homolog 2; BSP: Bone sialoprotein; DSPP: Dentin sialophosphoprotein; OCN: Osteocalcin.

Figure Lengend Snippet: Overexpression of enhancer of zeste homolog 2 enhances osteo/dentinogenic differentiation potential of human apical papillary stem cells. A: Quantitative polymerase chain reaction showed that enhancer of zeste homolog 2 (EZH2) was overexpressed in human apical papillary stem cells (hSCAPs); B: Western blot analysis confirmed overexpression of EZH2 in hSCAPs; C: Overexpression of EZH2 increased alkaline phosphatase activity in hSCAPs; D and E: Alizarin red staining and quantitative calcium analysis results demonstrated that overexpression of EZH2 enhanced mineralization in hSCAPs; F-H: Quantitative polymerase chain reaction showed that overexpression of EZH2 upregulated mRNA expression levels of bone sialoprotein (F), dentin sialophosphoprotein (G), and osteocalcin (H) in hSCAPs; I: Hematoxylin-eosin staining and quantitative measurement showed that overexpression of EZH2 promoted bone/dentin-like tissue formation. Scale bar = 100 μm (B: Bone/dentin-like tissues; HA: Hydroxyapatite tricalcium carrier; CT: Connective tissue); J: Immunohistochemical staining and quantitative analysis of dentin sialophosphoprotein and bone sialoprotein. GAPDH and ACTB were used as the internal controls. Data are presented as the mean ± SD ( n = 3). Statistical analysis was performed using Student’s t -test. a P ≤ 0.05, b P ≤ 0.01, c P ≤ 0.001.
