Objective To explore the mechanism for differentiation of osteoblasts induced by Asperosaponin Ⅵ in bone marrow mesenchymal stem cells(BMSCs)of rats. Methods BMSCs were cultured with whole bone marrow adherent method. The achieved cells were divided into 5 groups, namely induction group, 1 μmol/L asperosaponin Ⅵ group,1 μmol/L asperosaponin Ⅵ plus 5 μmol/L SP inhibition group,1 μmol/L asperosaponin Ⅵ plus 10 μmol/L SP inhibition group,1 μmol/L asperosaponin Ⅵ plus 20 μmol/L SP inhibition group.
