Japanese DC immune cell therapy. Japanese DC therapy is the most widely used immune cell therapy in the world. After DC cells are cultured in vitro to enhance their anti-cancer ability, they are returned to patients to transmit the information of cancer antigen, so that immune cells can fight cancer cells together. DC cells have immune memory. When cancer cells are found again, they can quickly and effectively transmit attack signals to other immune cells, so that the immune system can attack cancer cells in a short time, improve the immunity of patients, and effectively prevent cancer metastasis and recurrence.
