So now NK cell immunotherapy has considerable prospects, and it does not require genetic modification.
The NK cell therapy process begins with drawing the patient¡¯s blood, followed by isolating and purifying the NK cells in a laboratory or controlled system. Through cell culture technology and the addition of specific cytokines, NK cells proliferate and activate in large quantities in about 14 days. Finally, these cultured and activated NK cells are reintroduced into the patient to target and destroy cancer cells. Therefore, immune cell therapy attaches great importance to maintaining cell quality and ensuring safety. Whether in immune cell therapy or cytotoxicity experiments, cell survival rate is a key indicator.
