Abstract
To explore the effects of the shock wave on the capacity of mesenchymal stem cells(MSCs) to proliferate and differentiate into osteoblasts. 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. 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. The shock wave treatment can promote proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells.
