摘要: 目的:探讨超短波对鼠骨髓间充质干细胞(rat bone marrow mesenchymal stem cells,rBMSCs)增殖及成骨分化能力的影响。方法:体外分离培养rBMSCs,取第2~4代rBMSCs置于超短波理疗仪上进行处理,1次/d,15 min/次,于1、4、7 d检测细胞增殖能力,3 d后检测细胞碱性磷酸酶(alkaline phosphatase,ALP)分泌量,7 d后检测成骨基因Runx2表达量。结果:每日给予超短波处理的实验组细胞经连续培养7 d后,与不经超短波处理的对照组相比,其增殖能力明显提升(P<0.05),Runx2表达明显上调(P<0.05),ALP分泌量增多; 结论:超短波能促进SD大鼠rBMSCs增殖和成骨分化。

Abstract: Objective: To investigate the effect of ultrashort wave on the proliferation and osteogenic differentiation of rat bone marrow mesenchymal stem cells (rBMSCs). Methods: rBMSCs were isolated from SD rats and treated by ultrashort wave fields for 15mins/d. Cell proliferation was determined by CCK-8 method after 1, 4 and 7d respectively. Intracellular alkaline phosphatase (ALP) activity was measured by BCTP/NBT kit after the cells were cultured for 3d. Real-time PCR was used to compare the expression of osteogenesis related gene runt-related transcription factor-2 (RUNX2) after the cells were cultured for 7d. Results: Ultrashort wave significantly enhanced the proliferation (P<0.05) and osteogenic differentiation of rBMSCs, which was indicated by the high ALP production and up-regulated RUNX2 (P<0.05). Conclusion: Ultrashort wave promoted the proliferation and osteogenic differentiation of rBMSCs.
