文题释义:
麝香酮:
是从鹿科动物林麝Moschus berezovskii Flerov或原麝Moschus moschiferus L。成熟雄体香囊中的干燥分泌物麝香经蒸馏提取得到的活性成分之一,学名为3-甲基十五烷酮,是麝香的主要香味成分。
细胞标记:是指在多细胞系统中,为了追踪调查某特定细胞(群)的作用和行为,把作为对象的细胞(群)加以标记。间充质干细胞的标记物为CD105?CD73和CD90≥95%,CD45?CD34?CD14?CD11b?CD79a?CD19或HLA-Ⅱ类分子< 2%?

 

摘要
背景:
骨髓间充质干细胞是多向分化干细胞,在骨折愈合和中有着重要作用。如何促进其在体内迁移,进而促进骨缺损的修复,有着重要研究意义。
目的:研究不同浓度麝香酮对外源性骨髓间充质干细胞在体内迁移的影响,探讨其促进骨折愈合的机制及其引经理论初探。
方法:建立大鼠颅骨缺损的大鼠模型;贴壁筛选法提取干细胞,取第3代细胞,利用DAPI进行标记,然后尾静脉回植入颅骨缺损的大鼠体内。分别以0,42,84,168 μL/kg麝香酮灌胃1次。
结果与结论:与高剂量麝香酮组和空白组相比,低、中剂量麝香酮组骨缺损部分的骨髓间充质干细胞数量增加,干细胞因子和Fractalkine的表达水平明显增加。提示中低剂量麝香酮具有促进外源性干细胞在体内的迁移作用。

Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are a kind of stem cells with multi-directional differentiation ability and play an important role in the healing of fractures. Therefore, it is of great significance to explore how to promote the BMSCs migration in vivo, thereby promoting bone defect repair.
OBJECTIVE: To study the effects of different concentrations of musk ketone on in vivo migration of exogenous BMSCs, and to preliminarily explore the mechanism of fracture healing and cited theory.  
METHODS: A rat model of skull defects was made. Passage 3 BMSCs were harvested by using adherence method, labeled with DAPI, and then injected via the tail vein into the model rats. After that, the rats were intragastrically administrated with 0 (blank control), 42 (low dose), 84 (middle dose), 168 μL/kg (high dose) musk ketone, respectively.
RESULTS AND CONCLUSION: The number of exogenous BMSCs in the defect region, and the expression of stem cell factor and Fractalkine showed a significant increase in the low- and middle-dose groups compared with the high-dose and blank control groups. These findings indicate that the low- and middle-dose musk ketone can promote the in vivo migration of exogenous stem cells.
