1、ChineseJournalofRehabilitationMedicine,Jul.2013,Vol.28,No.7·基础研究·次声对大鼠骨髓间充质干细胞分泌存活素能力影响的研究11,2111何任红范建中吴红瑛李德洁毕迎立摘要目的:探讨次声对骨髓间充质干细胞(BMSCs)分泌存活素(survivin)能力的影响,初步探讨次声提高BMSCs增殖活性和抑制凋亡的机制。方法:应用全骨髓培养法获取SD大鼠原代的BMSCs,培养传代,取第三代细胞分为次声干预组与空气暴露组,两组的处理时间均为60min。采用免疫荧光技术检测两组细胞存活素表达
2、的情况。结果:次声处理组的存活素阳性细胞率(59.9±6.1),空白对照组存活素阳性细胞率(24.3±5.8),两组具有显著性差异(P<0.05)。从荧光发光强度来看次声处理组BMSC单个细胞表达存活素的荧光强度也明显大于对照组。结论:经次声作用的BMSCs在培养72h后其存活素的表达能力明显大于空气暴露组,说明次声促进BMSCs增殖、抑制其凋亡的可能机制之一为次声提高了BMSCs分泌存活素的能力。关键词次声;骨髓间充质干细胞;存活素中图分类号:R329.2,R49文献标识码:A文章编号:1001-1242(2013)-07-060
