From One Stem Cell to Millions of Cancer Killers
A three-step engineering strategy generates vast numbers of potent NK immune cells – potentially slashing the cost and scaling of cancer immunotherapy
-
1
Scientists in China have developed a method to mass-produce cancer-fighting NK cells from a single stem cell.
-
2
The new approach uses early-stage cord blood stem cells, achieving higher yields and improved consistency in cell therapy.
-
3
The three-step process includes expansion, differentiation, and large-scale maturation of CD34+ hematopoietic stem cells.
-

In leukemia mouse models, CAR-engineered NK cells suppressed tumor growth and retained potency after cryopreservation.
