Abstract:

BACKGROUND: Generally considered bone marrow cells obtained by adherent method are mesenchymal stem cells, and they can differentiate into osteoblasts, adipocytes and chondrocytes.
OBJECTIVE: To explore the differentiation capacity of bone marrow adherent cells into osteoclasts.
METHODS: Primary mouse mesenchymal stem cells were obtained using adherent method, and bone marrow cells were obtained through adherence 1-5 days. Both of them were cultured with normal medium and inducing medium containing m-csf and RANKL. After 9 days, cells were stained by alkaline phosphatase and tartrate-resistant acid phosphatase. The passage 2 mesenchymal stem cells were divided into four groups, which were induced by mock, m-csf, RANKL and m-csf+RANKL, respectively. After 9 days of culture, the cells were stained by alkaline phosphatase and tartrate-resistant acid phosphatase.
RESULTS AND CONCLUSION: Primary culture of adhered cells was uniform. Alkaline phosphatase and tartrate-resistant acid phosphatase staining of primary and passaged bone marrow adherent cells induced with m-csf+RANKL were positive. This result showed that there were cells that could be induced into osteoclasts in the primary and passaged bone marrow adherent cells. Alkaline phosphatase and tartrate-resistant acid phosphatase  staining showed differences of adherent cells at different times after the induction, indicating that adherent cells at different times had different differentiation capacity.
