• One stem cell generates 14 million tumor-killing NK cells in major cancer breakthrough Researchers in China have created a more efficient strategy for producing natural killer (NK) cells for use in cancer immunotherapy. • NK cells play a critical role in the body’s early defense against viruses and cancer, along with other immune functions. • Because of their natural ability to detect and destroy abnormal cells, they are an attractive tool for cancer treatment. • In chimeric antigen receptor (CAR)-NK therapy, scientists equip NK cells with a lab-designed receptor (a CAR) so they can recognize a specific marker on cancer cells and attack them more precisely. • Traditional CAR-NK approaches usually depend on mature NK cells collected from sources such as peripheral blood or cord blood. • This method presents several obstacles, including wide variability between cells, limited efficiency during genetic modification, high production costs, and lengthy preparation times.
