Abstract Background SDF-1α cotreatment was shown to have synergistic effects on BMP-2-induced odontogenic differentiation of human apical dental papillary stem cells (SCAP) both in vitro and in vivo. Long noncoding RNAs (lncRNAs) have an important role in the odontogenic differentiation of dental pulp stem cells (DPSCs). Methods We examined the altered expression of lncRNAs in SDF-1α-induced odontogenic differentiation of DPSCs by lncRNA microarray and quantitative reverse transcription polymerase chain reaction (qRT-PCR) analyses. Alterations in lncRNA expression during odontogenic differentiation of DPSCs were identified. Moreover, bioinformatic analysis [Gene Ontology (GO) analysis and coding-noncoding gene coexpression (CNC) analysis] was conducted to predict the interactions of lncRNAs and identify core regulatory factors in SDF-1α-induced odontogenic differentiation of DPSCs. Results The microarray analysis identified 206 differentially expressed lncRNAs (134 lncRNAs with upregulated expression and 72 with downregulated expression) at 7 days post‑treatment. The data demonstrated that one lncRNA, AC080037.1, regulates SDF-1α-induced odontogenic differentiation of DPSCs. Our data showed that lncRNA AC080037.1 siRNA suppresses DPSCs migration and the expression of Rho GTPase induced by SDF-1α. Moreover, AC080037.1 knockdown significantly affected SDF-1α- and BMP-2-induced mineralized nodule formation and strongly suppressed Runt-related factor-2 (RUNX-2), DMP-1 and DSPP expression in DPSCs.

And Migration

Pentraxin-3 (PTX3) is recognized as a modulator of inflammation and a mediator of tissue repair. In this study, we characterized the role of PTX3 on some biological functions of human dental pulp stem cells (HDPSCs). The expression level of PTX3 significantly increased during osteogenic/odontogenic differentiation of HDPSCs, whereas the knockdown of PTX3 decreased this differentiation. Silencing of PTX3 in HDPSCs inhibited their migration and C-X-C chemokine receptor type 4 (CXCR4) expression. Our present study indicates that PTX3 is involved in osteogenic/odontogenic differentiation and migration of HDPSCs, and may contribute to the therapeutic potential of HDPSCs for regeneration and repair.

Background: Tooth tissue regeneration mediated by mesenchymal stem cells (MSCs) has become the most ideal treatment. Although the known regulatory mechanism and some achievements have been discovered, directional differentiation cannot effectively induce regeneration of tooth tissue. In this study, we intended to explore the function and mechanism of miR-6807-5p and its target gene METTL7A in odontogenic differentiation.Methods: In this study, human dental pulp stem cells (DPSCs) were used. Alkaline phosphatase (ALP), Alizarin red staining (ARS), and calcium ion quantification were used to detect the odontogenic differentiation of miR-6807-5p and METTL7A. Real-time RT-PCR, western blot, dual-luciferase reporter assay, and pull-down assay with biotinylated miRNA were used to confirm that METTL7A was the downstream gene of miR-6807-5p. Protein mass spectrometry and co-immunoprecipitation (Co-IP) were used to detect that SNRNP200 was the co-binding protein of METTL7A.Results: After mineralized induction, the odontogenic differentiation was enhanced in the miR-6807-5p-knockdown group and weakened in the miR-6807-5p-overexpressed group compared with the control group. METTL7A was the downstream target of miR-6807-5p. After mineralized induction, the odontogenic differentiation was weakened in the METTL7A-knockdown group and enhanced in the METTL7A-overexpressed group compared with the control group. SNRNP200 was the co-binding protein of METTL7A. The knockdown of SNRNP200 inhibited the odontogenic differentiation of DPSCs.Conclusion: This study verified that miR-6807-5p inhibited the odontogenic differentiation of DPSCs. The binding site of miR-6807-5p was the 3′UTR region of METTL7A, which was silenced by miR-6807-5p. METTL7A promoted the odontogenic differentiation of DPSCs. SNRNP200, a co-binding protein of METTL7A, promoted the odontogenic differentiation of DPSCs.
