ABSTRACT
Objective:
To observe the differential expression of miRNAs between human dental pulp stem cells(DPSCs) and stem cells from the apical papilla(SCAPs).Methods:
DPSCs and SCAPs were isolated by immune-magnetic binding specific STRO-1 antibody separation system. Osteogenic and adipogenic differentiation of DPSCs and SCAPs were tested by ALP assay, alizarin red staining(ARS) and Oil Red O staining. Differential miRNA expression of DPSCs and SCAPs was screened by the Next generation sequencing. Target genes and their possible roles of these differential miRNAs were predicted using biological information analysis.Results:
The results revealed that 7 miRNAs(hsa-miR-224-5p, hsa-miR-1247-5p, hsa-miR-3065-3p, hsa-miR-452-5p, hsamiR-767-5p, hsa-miR-4284, hsa-miR-146a-5p) were downregulated while no miRNAs was upregulated in SCAPs compared with DPSCs. 27 target genes which mainly involved in the cell migration, differentiation and apoptosis were found.Conclusion:
Downregulation of some specific miRNAs might be related to the stemness of SCAPs.
