Effector cell combination for preventing and treating tumors and preparation method thereof

The invention relates to an effector cell combination for preventing and treating tumors. The effector cell combination comprises CIK (cytokine induced killer) cells and MSC (Mesenchymal Stem Cells) which are sequentially injected into a human body in the form of a cell suspension and are extracted and prepared from peripheral blood of exogenous healthy people in non-tumor patients. The invention also discloses a preparation method of the effector cell combination, and the method comprises the following steps of: blood mononuclear cell collection, CIK cell culture and MSC culture. According to the scheme disclosed by the invention, the CIK cells and the MSC are extracted and prepared from the peripheral blood of the exogenous healthy people in the non-tumor patients, thereby breaking the routine treatment of auto-CIK cells, improving the clinical effects of tumor biotherapy and especially the clinical effects of CIK cell therapy, and solving the problems in graft-versus-host reaction (GVHD).
