[Effect of Naringin on proliferation and osteogenic differentiation of bone marrow stromal cells in vitro].

PURPOSE: To investigate the differentiation and osteogenic activity of Naringin-induced bone marrow stromal cells (BMSCs) in dogs. METHODS: BMSCs were separated and cultured in vitro and identified by FCM. Then different concentration of Naringin (1×10⁻5, 1×10⁻6, 1×10⁻7, 1×10⁻8 and 1×10⁻9 mol/L) were added to cell culture media to induce BMSCs. The effect of Naringin on BMSCs was evaluated respectively by CCK-8 method and measuring the activity of alkaline phosphatase (ALP). The formation of nodules of calcium was detected by von Kossa staining. The data was analyzed with SPSS20.0 software package. RESULTS: The result of cell-surface marker displayed that the expression of CD34 and CD45 were negative while the expression of CD90 was positive. The values were 0.126%, 0.075% and 95.4%, respectively. Naringin could obviously promote cell proliferation, which exhibited the best effect on proliferation and osteogenic differentiation at concentration of 10-6 mol/L. Calcium nodule (von Kossa) staining was positive. CONCLUSIONS: Naringin-induced bone marrow stromal cells can be differentiated into osteoblasts. Naringin at the concentration of 10-6 mol/L can enhance the proliferation and osteogenic differentiation of BMSCs.
