Abstract

The invention provides a culture medium for human-derived T lymphocytes. Each 1L of the culture medium comprises the following components: 80-120 mL of human AB serum, 7-15 mL of an MEM vitamin solution, 7-12 mM of N-acetyl-L-cysteine, 1.6-2.5 mM of glutamine or a derivative, 0.8-1.2 mM of sodium pyruvate, 15-25 mM of 4-hydroxyethyl piperazine sodium esilate, 4-6 mu g of IL-7, 6-9 mu g of IL-15 or heterodimer thereof, and the balance of X-VIVO basic culture medium, wherein the glutamine or the derivative thereof comprises glutamine or L-alanyl-L-glutamine. The culture medium can be used for culturing antigen specific T lymphocytes, the cell proliferation rate of the antigen specific T lymphocytes can be increased, and the tumor killing ability can be high. The invention further provides a preparation method and application of the culture medium.

Description

technical field [0001] The invention relates to the field of biological cell culture, in particular to a culture medium of human T lymphocytes and a preparation method and application thereof. Background technique [0002] Cancer has always been a huge problem plaguing mankind. Although surgery, chemotherapy, radiotherapy and other treatments can greatly improve the survival rate of cancer patients, these treatments are far from enough to save tens of millions of cancer patients around the world. With the rapid development of biotechnology, tumor immune cell therapy has become the fourth largest therapy in the field of cancer treatment. It can make up for the shortcomings of traditional therapy and is considered to be the most promising treatment in the comprehensive tumor treatment model in the 21st century. It uses biotechnology and biological agents to separate immune cells from patients, culture, activate and expand them in vitro, and then infuse them back into patients...
