[Effects of Shock Wave on the Proliferation and Osteogenic Differentiation of Human Bone Marrow Mesenchymal Stem Cells].

Objective: To explore the effects of the shock wave on the capacity of mesenchymal stem cells(MSCs) to proliferate and differentiate into osteoblasts.

Methods: MSCs were isolated from the bone marrow of healthy donors. The human bone marrow MSCs(BM-MSCs) were divided into 3 groups including blank control group,osteoinduced group and shock wave group. The MSCs in blank control group were cultured with common mediam; the MSCs in osteoinduced group were treated with osteogenic agents and cultured; the MSCs in shock wave group were cultured with common medium and stimulated by shock wave. The morphology of MSCs in each groups were observed by micoscopy; the CCK-8 was used to detect the proliferation ability of MSCs; the alkaline phosphatase staining and von Kossa staining were used to evaluale the differentiation potential of MSCs in each groups.

Results: The results of CCK-8 revealed the shock wave could promote cell proliferation as compared with blank control group. The results of alkaline phosphatase and Von Kossa staining showed that the shock wave displayed a stronger ability to promote the human BMMSC differentiation into osteoblasts cells in comparison with the osteoinduced group. The blank control group was weakly positively stainined.

Conclusion: The shock wave treatment can promote proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells.
