中文摘要：

间充质干细胞因具有心肌细胞分化潜能和易于获取等特点而被应用于心肌梗死后心肌组织的修复,可改善心肌梗死后的心功能。但无论是经静脉注射、冠脉注射还是心肌内注射等移植方式均面临干细胞归巢率低的问题。SDF-1/CXCR-4通路在多种干细胞的归巢过程中发挥重要作用,研究者使用了多种方法来增强该通路的功能以达到提高干细胞归巢效率的目的。本文就近年来增强SDF-1/CXCR-4通路功能的方法和该通路在间充质干细胞归巢中的作用机制进行综述。

英文摘要：

Mesenchymal stem cells（MSCs）, for their potential of differentiation into cardiomyocytes and easy acquisition, have been used in repair of myocardium tissue and improvement of heart functions after myocardial infarction. However, a vexed problem is the low homing rate of MSCs no matter what delivery methods（including intravenous, intracoronary or endocardial delivery） are used. SDF-1/CXCR-4 signal pathway plays an important role in variety of stem cell homing, and has been employed to enhance the function of SDF-1/CXCR-4 signal pathway for improving the efficiency of stem cell homing. The present paper has reviewed the methods used recent years to enhance the function of SDF-1/CXCR-4 signal pathway and the mechanism of the signal pathway in MSCs homing.
