摘要(Abstract)：

[目的]观察冲击波(shock waves)与地塞米松对自体血清培养的人骨髓间充质干细胞(hum an m esenchy-m al stem cells,hMSCs)体外成骨分化的影响比较。[方法]选择10名健康志愿者,每名健康志愿者抽取骨髓60 m l,抽取外周静脉血100 m l,然后分离出自体血清。把每名志愿者的骨髓分别用10%AS和10%FBS对hMSCs进行体外培养,通过相差倒置显微镜观察细胞形态、检测24 h细胞贴壁率、细胞倍增时间、检测细胞表面标记物、细胞周期及免疫细胞化学染色检测比较两组hMSCs的增殖状况。然后把AS培养的hMSCs两组分别用体外冲击波疗法(extracor-poreal shock waves therapy,ESWT)[0.36 m j/(mm2.100次)]和传统的诱导成骨培养基(10 nmol/L地塞米松、50umol/L抗坏血酸、10 mmol/Lβ-甘油磷酸钠)分别对hMSCs进行成骨诱导,对诱导好的细胞进行ALP定量检测、ALP染色、茜素红染色及RT-PCR测成骨基因(碱性磷酸酶、骨钙素、骨桥蛋白、骨结合素、I型胶原)表达比较两组成骨分化情况。[结果]在细胞增殖上,两组细胞各代在细胞形态、细胞贴壁率、细胞周期以及免疫细胞化学染色检测上无明显差异,但在细胞倍增时间、细胞增殖速率上,自体血清明显优于胎牛血清。在细胞分化方面,两组在ALP定量检测、ALP染色、茜素红染色及RT-PCR测成骨基因上,冲击波作用于人骨髓间充质干细胞的成骨效应明显优于地塞米松。[结论]冲击波与地塞米松相比较,具有更良好促hMSCs成骨分化作用。
