[Effects of Epimedium pubescens icariine on proliferation and differentiation of human osteoblasts].

OBJECTIVE

To study the effects of epimedium pubescens icariine on the proliferation and differentiation of human osteoblasts.

METHOD

Human osteoblasts were obtained by inducting human marrow mesenchymal stem cells (hMSCs) directionally. MTT was used to observe the proliferation and activity of ALP was assayed to observe the differentiation of the third passage human osteoblasts cultured in vitro. The expression of BMP-2 mRNA was checked by RT-PCR.

RESULT

Epimedium pubescens icariine at the dose of 20 microg x mL(-1) increased greatly the proliferation and differentiation of human osteoblasts and promoted the expression of BMP-2 mRNA.

CONCLUSION

Epimedium pubescens icariine enhances significantly the proliferation and differentiation of human osteoblasts, which may be mediated by increasing the expression of BMP-2 mRNA.
