Objective:To observe the effect and mechanism of Icariin on proliferation and differentiation of osteoblasts Methods:The preosteoblastic cell lines OCT1 cells were cultured under the routine method, then intervened for 48 hours with Icariin, at the concentration of 10ug/mL, 30ug/mL and 60ug/mL respectively, and the purified protein BMP2 (50μg/L) as a positive control. MTT method was performed to detect the proliferation rate of osteoblasts, and RT-PCR analysis was performed to observe the expression of BMP2 mRNA, Runx2 mRNA Results:Compared with the normal control group, Icariin promoted the osteoblast proliferation obviously (P<0.05); Icariin increased the expression of BMP2 mRNA and Runx2 mRNA in osteoblasts significantly (P<0.05) Conclusion:Icariin can induce the proliferation and differentiation of osteoblasts by activating the BMP signaling pathway and up-regulating the expression of Runx2 in preosteoblastic cell lines.
