    Abstract: The present invention relates to a composition for enhancing a survival rate of stem cells, including an immunosuppressant, and to a use thereof. According to the present invention, a survival rate of stem cells can be remarkably enhanced using a composition including an immunosuppressant, and a therapeutic effect of stem cells can be improved on the basis of the enhancement. The composition can overcome an immune response caused by the administration of xenogeneic cells so as to accurately verify the stability and efficacy of cells, and thus will be able to be utilized as a mesenchymal stem cell therapeutic agent that maximizes a therapeutic effect of stem cells.
