Objective: To investigate the effects of main Epimedii Folium flavonoids (epimedin A
epimedin B
epimedin C
icariin and icarisid Ⅰ) on promoting BMSCs proliferation and differentiation into osteoblasts and to predict the mechanism of them. Method: BMSCs in SD rats were isolated and purified by whole bone marrow adherence method for primary culture. The experiment was divided into 6 groups: epimedin A+ osteogenic medium (1×10-8 mol·L-1)
epimedin B+ osteogenic medium (1×10-8 mol·L-1)
epimedin C+ osteogenic medium (1×10-8 mol·L-1)
icariin + osteogenic medium (1×10-8 mol·L-1)
icariside group + osteogenic medium (blank group). After drug intervention for 14 days
qualitative and quantitative methods were combined for pharmacodynamic evaluation
of the above 5 kinds of Epimedii Folium flavonoids by alizarin red staining
cytoskeleton staining and alkaline phosphatase assay. Meanwhile
the potential targets and pathways were predicted and analyzed based on BATMAN-TCM network pharmacology research platform to investigate the action mechanisms. Result: BMSCs were treated with 1×10-8 mol·L-1 drugs for 14 d
and polygonal osteoblasts were increased in various groups by cytoskeleton staining; in alizarin red staining
a large number of mineralized nodules were formed in various treatment groups; in Alkaline phosphatase assay
the content of alkaline phosphatase was increased in various treatment groups as compared with the blank group
particularly
the groups of epimedin C(P<0.05)
icariin (P<0.05)
and icarisid Ⅰ(P<0.01) showed significant changes. As for network pharmacology analysis
33 potential targets and 8 pathways about proliferation and differentiation were obtained. Among them
activation of MAPK activity and estrogen signaling pathway had been verified by the relative experimental reports. Conclusion: All of the above 5 kinds of Epimedii Folium flavonoids could promote BMSCs proliferation and differentiation into osteoblasts. especially
epimedin C
icariin
and icarisid Ⅰ had significant effects. The results of network pharmacology analysis interpreted the overall mechanism of the Epimedii Folium flavonoids
