  • Method of differentiating hematopoietic stem cells into natural killer cells using YC-1 or IL-21
    Patent number: 8318491
    Abstract: The present invention relates to an agent for differentiating hematopoietic stem cells into natural killer cells and a method for the differentiation, more precisely an agent for differentiating hematopoietic stem cells into natural killer cells comprising YC-I [3-(5?-hydroxymethyl-2?-furyl)-1-benzylindazole] or IL-21 (Interleukin-21) as an active ingredient and a method for differentiating hematopoietic stem cells into natural killer cells using the same. The YC-I and IL-21 regulate the differentiation of hematopoietic stem cells into natural killer cells and increase the killing activity of NK cells. Therefore, the agent for NK cell differentiation of the present invention can be effectively used for cell therapy for the treatment of cancer by regulating the differentiation of hematopoietic stem cells into natural killer cells having tumor cell killing activity.
