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.

Abstract Background Human periodontal ligament stem cells (hPDLSCs) are one of the most promising types of seed cells in periodontal tissue regeneration. Suitable biomaterials are additional essential components that must cooperate with seed cells for in vivo expansion or in vitro implantation. Extracellular matrix (ECM) derived from mesenchymal stem cells (MSCs) was recently reported to be a promising substrate with which to culture MSCs that could be applied in biomaterial scaffolds or bioink. Human urine-derived stem cells (hUSCs) have several advantages; their collection is non-invasive and easy, and hUSCs are low in cost, potentially making them a suitable and efficient source of ECM. The purpose of this study was to characterize the biological properties of ECM derived from hUSCs (UECM) and evaluate the effects of UECM on hPDLSCs. Methods hPDLSCs grown on ECM derived from hPDLSCs (PECM) and fibronectin-coated tissue culture plastic (TCP) served as control groups. Both hUSCs and hPDLSCs were seeded on TCP and stimulated to produce ECM. After 8 days of stimulation, the samples were decellularized, leaving only ECM. Then, hPDLSCs were seeded onto UECM-, PECM-, and fibronectin-coated TCP and untreated TCP. Results UECM consists of dense bundles of fibers which contain abundant fibronectin. Both UECM and PECM promoted hPDLSC proliferation, attachment, spreading, and differentiation. Between UECM and PECM, UECM enhanced proliferation, osteogenesis, and angiogenesis to a greater extent. Though fibronectin appeared to be the abundant component of UECM, its performance was inferior to that of UECM. Conclusions Our study provides an original perspective on different cell-specific ECMs and suggests UECM as a suitable biomaterial in which to culture hPDLSCs as UECM enhances their biological functions.

Pdl Cells

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.
