Abstract: BACKGROUND: Naringenin has various physiological activities such as anti-bacterial, anti-inflammatory, anti-fibrosis, and anti-oxidation, and is widely used in the fields of medicine and food. Recent studies have shown that naringenin can effectively promote the osteogenic differentiation of mesenchymal stem cells, but it is unclear whether naringenin regulates the osteogenic differentiation of periodontal ligament stem cells.
OBJECTIVE: To investigate the effects of naringenin with different concentrations on the osteogenic differentiation of human periodontal ligament stem cells. 
METHODS: The primary human periodontal ligament stem cells were isolated and cultured. After treatment with naringenin at concentrations of 10, 100 nmol/L, 1, 10, 100 μmol/L and 1 mmol/L for 72 hours, the cytotoxicity of naringenin on periodontal ligament stem cells was measured via CCK-8 assays. The third generation of human periodontal ligament stem cells was cultured with osteogenic medium containing 0, 1, 10 and 100 μmol/L naringenin respectively. Alkaline phosphatase staining and activity detection were performed after 3, 5, and 7 days. Real-time PCR was used to detect the expression of osteogenic factors including Runx2, osteopontin and osteocalcin in human periodontal ligament stem cells after induction for 7 days. Alizarin red staining and quantitative determination of mineralized nodule were performed after induction for 14 days. 
RESULTS AND CONCLUSION: Naringenin at a concentration of 10 nmol/L-100 μmol/L has no cytotoxicity to human periodontal ligament stem cells, and naringenin at a concentration of 1 mmol/L has obvious cytandotoxicity to human periodontal ligament stem cells. An appropriate concentration of naringenin (1-100 μmol/L) significantly promotes the increase of alkaline phosphatase activity and mineral deposition and upregulates the gene expression of Runx2, osteopontin and osteocalcin. The results showed that naringenin can significantly promote the osteogenic differentiation of human periodontal ligament stem cells, and the ability to promote osteogenic differentiation is strongest at 100 μmol/L.
