    Abstract:
    A capsule of Qili Jiegu, a traditional Chinese medicine with numerous biological activities, may exert a protective eff ;ect against postmenopausal bone loss. However, it remains unclear whether Qili Jiegu-containing serum regulates the osteogenic diff ;erentiation of bone marrow stromal cells (BMSCs) in vitro. In this study, BMSCs were treated with medium and Qili Jiegu-containing serum over a 14-day period. We found that Qili Jiegu-containing serum promoted the BMSC proliferation and alkaline phosphatase (ALP) activities, as well as stimulated the expression of osteogenic markers and Wnt/β-catenin pathway-related genes, i.e., runt-related transcription factor 2 (Runx2), osteocalcin (OCN), β-catenin and Wnt4a, in BMSCs. Finally, we found that Qili Jiegu-containing serum activated the Wnt/β-catenin pathway. An addition of Dickkopf-related protein-1 (an inhibitor of the Wnt/β-catenin signaling pathway) to the Qili Jiegu-containing serum could decrease the stimulatory osteogenic effect of Qili Jiegu-containing serum on BMSCs. Therefore, Qili Jiegu-containing serum could promote the osteogenic diff ;erentiation of BMSCs, and the potential mechanism may involve regulation of Wnt/β-catenin signaling.
