间充质干细胞胰岛样细胞分化研究进展

间充质干细胞是存在于成体多种器官的多能干细胞,具有多胚层分化能力.近年研究发现在体内体外特定微环境作用下,它可以分化为胰岛样细胞,分泌一定量的胰岛素,并且具有降血糖的功能.这一技术可以同时解决胰岛移植中供体紧缺及免疫排斥反应两大难题,为临床糖尿病细胞治疗开辟了一条新的途径.

Recent progress in differentiation of mesenchymal stem cells into islet-like cells

Mesenchymal stem cells (MSCs) are multipotent stem cells existing in multi-organs and can differentiate into several kinds of somatic cells. Recently it has been found that MSCs, under defined conditions in vivo or in vitro, can be induced to trans-differentiate into islet-like cells, which can secrete a small amount of insulin and lower blood glucose levels in diabetic mice. Thus, two major obstacles of islet transplantation, the insufficience of donor islets and immunologic rejection, might be solved simultaneously with this technique. This finding provides a new insight into treatment for diabetes.
