Abstract
Background: The stimulating effects of apigenin on mesenchymal stem cells (MSCs) osteogenesis, as well as the anti-inflammatory effect of this flavonoid, have been identified. In this study, osteogenic differentiation was investigated under inflammatory conditions and treatment with apigenin. Methods and Results: Along with osteogenic differentiation of MSCs, they became inflamed with LPS/PA, and treated simultaneously with apigenin. The degree of differentiation was assessed by alizarin red staining and alkaline phosphatase (ALP) activity. Also, gene expression of NLRP3 and RUNX2 was performed along with protein expression of IL-1β. Significant increase in NLRP3 and IL-1β were observed in MSCs when exposed to LPS/PA (p<0.01). Also, the osteogenesis was significantly decreased (p<0.01). Apigenin treatment induced significantly higher gene expression of RUNX2, the activity of ALP, and cell staining (p<0.01) which were also associated with reduced inflammation in these cells. Conclusions: The effectiveness of apigenin on osteogenesis under inflammatory conditions was cautiously observed.
