Embodiment 1

[0052] (1) Isolation of mononuclear cells from whole blood:

[0053] 5 ml of human peripheral venous blood was collected, centrifuged at 2500 rpm for 10 min, and the upper layer of autologous plasma was taken for retention, and then stored in a 4 °C refrigerator after being bathed at 56 °C for 30 min. The volume ratio of the blood cell suspension in the lower layer is 1:1, and 3 ml of normal saline is added to dilute, and the mixture is mixed to obtain a blood cell dilution. Take a new centrifuge tube, add 5ml of neutrophil separation solution according to the volume ratio of blood cell dilution solution of 1:1, slowly add blood cell suspension to the upper layer of neutrophil separation solution, and centrifuge at 550g for 30min. After centrifugation, the layers were separated, the mononuclear cell layer was sucked, and the mononuclear cells were collected by centrifugation at 250 g for 10 min.

Abstract

The invention relates to the technical field of cell culture, and in particular to a cell separation culture solution and a T cell separation culture method. The cell separation culture solution includes a culture solution A, a culture solution B, and a culture solution C, and the three culture solutions cooperate in synergy and work together, and are conducive to stimulating transformation of monocytes to CIK cells. According to the cell separation culture solution and the T cell separation culture method, by adding neutrophil separation fluid to blood cells, content of neutrophils in the cells is reduced; after mononuclear cells are extracted by using the neutrophil separation liquid, most of red blood cells in mononuclear cell layer are removed by using a red blood cell lysis liquid, content of the red blood cells in the mononuclear cells is obviously reduced, and number of lymphocytes is increased; after the final culture, effective cell proportion in the cells is increased, and tumoricidal activity of cell population is increased.

Description

technical field [0001] The invention relates to the technical field of cell culture, in particular to a cell separation culture medium and a method for T cell separation and culture. Background technique [0002] T cells are derived from lymphoid stem cells derived from bone marrow. After differentiated and matured in the thymus, they are distributed to immune organs and tissues throughout the body through lymphatic and blood circulation to exert immune function. [0003] Adoptive immune cell therapy refers to the isolation of immune active cells from the human body, expansion and functional identification in vitro, and then infusion into the human body, so as to directly kill tumors or stimulate the body's immune response to kill tumor cells. Adoptive T cell therapy mainly includes TIL, LAK, CIK, TCR-T, CAR-T and other categories. [0004] At present, culturing T cells in vitro usually includes the following four steps: isolation of mononuclear cells, activation induction,...
