The invention refers to a medium for expanding natural killer cells expressing the CD56 + CD3 − phenotype, comprising CellGro® SCGM to which has been added interleukin-2, anti CD3 antibodies, and optionally serum, as well as a method of expanding said natural killer cells, isolated from a mononuclear cell concentrate, by suspension and incubation in said medium. The expanded NK cells can be used for curative or prophylactic treatment of patients, especially cancer patients undergoing stem cell transplantation. |
