  • Title: [Icariin promotes osteogenic differentiation of rat bone marrow stromal cells in vitro].
    Author: Zhai Y, Ge B, Ma H, Ming L, Li Z, Cheng G, Zhou J, Chen K.
    Journal: Zhongguo Zhong Yao Za Zhi; 2010 Dec; 35(23):3219-22. PubMed ID: 21355254.
    Abstract:
    OBJECTIVE: To investigate the effects of icariin on the osteogenic differentiation of rat bone marrow stromal cells (rBMSCs). METHOD: rBMSCs were cultured by adherence screening method. Icariin was supplemented into the culture at 1 x 10(-5) mol x L(-1). The osteogenic differentiation markers including alkaline phosphatase (ALP) activity, CFU-F(ALP) and mineralized bone modulus were compared between the icariin-supplemented group and the control group. Total RNA was isolated and the gene expression of bFGF, IGF-1, Osterix(OSX) and Runx-2 was investigated by RT Real-time PCR. RESULT: Icariin significantly improved ALP activity, CFU-F(ALP) amounts and mineralized modulus. It also can enhance the mRNA level of bFGF, IGF-1, Osterix and Runx-2. CONCLUSION: Icariin enhances the osteogenic differentiation of rBMSCs significantly, which suggested that icariin has the potentiality to be a new drug of anti-osteoporosis or fracture healing.
