Objective:
To investigate the effects of icariin and it's main metabolites-icariside II on the osteogenic differentiation of rat bone marrow stromal cells (rBMSCs).
Methods:
rBMSCs were cultured by adherence screening method, icariin and icariside II were supplemented into the culture at 5 x 10(-5) mol/L respectively. The osteogenic differentiation markers including alkaline phosphatase (ALP) activity, CFU-F(ALp), osteocalcin secretion, calcium deposition and mineralized bone modulus were compared among the icariin-supplemented group, icariside II and the control. The gene expressions of bFGF, IGF-1, Osterix and Runx-2 were examined by RT-Real Time PCR.
Results:
Both icariside II and icariin significantly improved ALP activity, CFU-F(ALP) amount, osteocalcin secretion, calcium deposition and mineralized modulus. Besides, they enhanced the gene expressions of bFGF, IGF-1, Osterix and Runx-2. Icariside II was obviously stronger than icariin at the above activities.
Conclusion:
Icariside II is stronger than icariin at enhancing the osteogenic differentiation of rBMSCs, suggesting that icariin can be administered via oral and it's metabolites are the effective constitutes for antiosteoporosis activity.
