Scientists Turn One Stem Cell Into 14 Million Cancer-Fighting NK Cells

Chinese scientists have developed a revolutionary method to mass-produce natural killer (NK) cells for cancer treatment. Instead of modifying mature immune cells, they engineered early-stage stem cells from cord blood to create millions of tumor-fighting NK cells. A single stem cell can now generate 14 million cancer-hunting NK cells, including specialized CAR-NK versions designed to target specific cancers. This approach uses 140,000 times less viral material than traditional methods and could produce thousands of treatment doses from one cord blood unit. The breakthrough addresses major obstacles in cancer immunotherapy including high costs, limited cell numbers, and lengthy preparation times.
