SNHG1 expression in hDPSCs during the odontogenic differentiation and SNHG1 governs the odontogenic differentiation of hDPSCs. A Relative ALP, DMP-1, DSPP and SNHG1 expressions were measured by qRT-PCR at day 0, 3, and 7 under the mineralization induction condition. GAPDH was used for normalization. B The transfection efficacy of SNHG1 was measured by qRT-PCR in SNHG1 group and si-SNHG1 group, with GAPDH as a control. C The proliferation ability of hDPSCs was measured by CCK-8. D-G After SNHG1 overexpression or silence, relative ALP, DMP-1 and DSPP expression were measured by qRT-PCR and ALP, DMP-1 and DSPP expression were measured by Western blot at day 5 under the mineralization induction condition. H At 7 days after odontogenic induction, hDPSCs were performed with ALP staining and activity. I On the 14th day, Alizarin Red staining and quantification were performed. J The expression of DMP-1 and DSPP in transfected hDPSCs were also showed by Immunofluorescence Staining. Scale bar = 20 μm. *P < 0.05, **P < 0.01, ***P < 0.001
