Effect of Herba Epimedii flavone on the osteoblasts metabolism in vitro / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the effect of Herba Epimedii flavone (HEF) on the osteoblast metabolism in vitro.</p><p><b>METHOD</b>Osteoblast were obtained from new born rat calvaria by digestive enzymes. MTF, PNPP and RT-PCR were used to observe the proliferation, activity of ALP and mRNA expression of OPG and RANKL of cultured osteoblasts in vitro.</p><p><b>RESULT</b>It was found that HEF had the effect on stimulating cell proliferation, activity of ALP and the mRNA expression of OPG of cultured osteoblasts (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>HEF can promote the proliferation, the differentiation and the expression of OPG mRNA of the osteoblasts cultured in vitro.</p>
