Method for improving in-vitro amplification capability of stem cells

The invention provides a method for improving the in-vitro amplification capacity of stem cells, and belongs to the technical field of stem cells. According to the method provided by the invention, the growth of the human umbilical cord blood mesenchymal stem cells is promoted by adding the decurin into the culture medium, and the growth of the human umbilical cord blood mesenchymal stem cells can be promoted by regulating and controlling the cyclin. Meanwhile, it is found that the peucedanin can promote the tube forming capacity of the umbilical cord blood mesenchymal stem cells, and therefore the peucedanin can be used for preparing the medicine for promoting the angiogenesis of the umbilical cord blood mesenchymal stem cells and used for treating cardiovascular diseases. 本发明提供了一种提高干细胞体外扩增能力的方法，属于干细胞技术领域。本发明所提供的方法在培养基中添加紫花前胡苷来促进人脐血间充质干细胞的生长，紫花前胡苷可以通过调控细胞周期蛋白来促进人脐血间充质干细胞的生长。同时，本发明发现紫花前胡苷可以促进脐血间充质干细胞的成管能力，从而可将其用于制备促进脐血间充质干细胞血管形成的药物并用于治疗心血管疾病。
