Cell proliferation was evaluated using phase-contrast microscopy and cell differentiation was estimated using alkaline phosphatase activity. The effect of the combined herbal therapy(CUR + FLL) was also assessed in terms of mineralization in the extracellular matrix(ECM) of cultured cells. Further, to explore the molecular mechanisms of bone formation, time-dependent expression of bone-regulating protein biomarkers was also evaluated.Results: Combined herbal therapy(CUR + FLL) significantly upregulated the viability, proliferation and differentiation of MC3 T3-E1 cells compared to the monotherapy of CUR or FLL. The magnitude of ECM mineralization(calcium deposition) was also higher in MC3 T3-E1 cells treated with combined therapy.The time-dependent expression of bone-forming protein biomarkers revealed that the tendency of expression of these bone-regulating proteins was remarkably higher in cells treated with combined therapy.Conclusion: The co-administration of CUR and FLL had superior promotion of elements of bone regeneration in cultured cells, thus could be a promising alternative herbal therapy for the management of bone erosive disorders such as osteoporosis.展开更多
