Human Vgamma9Vdelta2T Cell Proliferation Culture Method and Culture Medium

Abstract

Provided are a human Vγ9Vδ2T cell proliferation method and a culture medium. The method comprises: first stimulating a human Vγ9Vδ2T cell with a culture medium containing interleukin-2 and phosphonic acid compounds, and then culturing the human Vγ9Vδ2T cell with a culture medium added with interleukin-15 and vitamin C to achieve proliferation culture. The culture medium additionally comprises interleukin-15 and vitamin C. Compared with a conventional proliferation method and a conventional culture medium, the method and the culture medium can improve the proliferation efficiency and cell purity of the human Vγ9Vδ2T cell. The human Vγ9Vδ2T cell obtained by culture in the method has stronger anti-apoptotic ability and longer cell survival time, and moreover, the expression level of critical killer molecules NKG2D thereof is higher, thereby having stronger killing ability to tumor cells.
