间充质干细胞体内迁移研究进展

In vivo Migration of Mesenchymal Stem Cells——Review

间充质干细胞(MSC)具有低免疫源性、多向分化、强大的支持造血和免疫调节功能,同时具有来源广泛,易于体外分离和扩增的特点,目前广泛应用于临床疾病的治疗。研究资料表明,MSC输注后广泛分布于受者各组织器官,然而MSC体内靶向迁移是达到临床治疗的高效性和安全性的关键所在,本文对静脉输注后MSC的体内分布特点和增强MSC体内靶向迁移策略研究的新进展作一综述。

mesenchymal stem cells （MSC） have the capacities of low immunogeneity, multiple differentiation, hemotopoitic supporting and immunoregulation. And due to their relative ease of availability and ex vivo expansion, the applications of MSC in the prevention and treatment of clinical disease have been rapidly expanded in the recent years. However, increasing investigations indicate that intravenously infused MSC widely distribute to various organs of the recipients. The two intended clinical goals of adoptive cellular therapy reached to the greatest efficiency. Therefore, the ideal candidate cells showed to have the capacity of site-specific relocation in vivo. In this review, the distribution characteristics of infused MSC and the recent research advances on the strategies to enhance targeted migration of MSCs are summarized.
