This study is to explore the osteogenesis potential of the human periodontal ligament stem cells (hPDLSCs) induced by naringin in vitro and in vitro. The results confirmed that 1 μM naringin performs the best effect and a collection of bone-related genes (RUNX2,COL1A2, OPN, and OCN) had significantly higher expression levels compared to the control group. Furthermore, a typical trabecular structure was observed in vivo, surrounded by a large amount of osteoblasts. These results demonstrated that naringin, at a concentration of 1 μM, can efficiently promote the proliferation and differentiation of hPDLSCs both in vitro and in vivo.

The existence of PDLSCs [PDL (periodontal ligament) stem cells] in PDL has been identified and such cells may function in periodontal reconstruction, including bone formation. Oestrogens/ERs (oestrogen receptors; ERα and ERβ) exert important effects in bone formation, however, the relationship between ERs and PDLSCs has not been established. In the present study, PDLSCs were isolated and assays for detecting stem-cell biomarkers and multipotential differentiation potential confirmed the validity of human PDLSCs. The results of RT–PCR (reverse transcription–PCR) and Western blotting showed that ERα and ERβ were expressed at higher levels in PDLSCs as compared with PDLCs (PDL cells), and 17β-oestradiol obviously induced the osteogenic differentiation of PDLSCs in vitro. Furthermore, a pan-ER inhibitor or lentivirus-mediated siRNA (small interfering RNA) targeting ERα or ERβ blocked the oestrogen-induced osteogenic differentiation of PDLSCs. The results indicate that both ERα and ERβ were involved in the process of osteogenic differentiation of PDLSCs.

Objective: The aim of this study was to compare the characteristics of periodontal ligament stem cells derived from supernumerary teeth (sPDLSCs), cultured using a three-dimensional (3D) method and a conventional two-dimensional (2D) method. Methods: The morphology, viability, and osteogenic differentiation of the cells were analyzed. In addition, gene expression was analyzed by RNA sequencing, to characterize the functional differences. Results: The diameter of the 3D-cultured sPDLSCs decreased over time, but the spheroid shape was maintained for 7 days. The osteogenic differentiation was similar in the 2D and 3D. The gene expression related to the extracellular matrix (7.3%), angiogenesis (5.6%), cell proliferation (4.6%), inflammatory response (3.7%), and cell migration (3.5%) differed (p < 0.05). Conclusions: Within the limitations of this study, sPDLSCs varied in formation and function, depending on the culture method. In future, it is necessary to study tissue engineering using the advantages of 3D culture and the fewer ethical problems of supernumerary teeth.
