CAR-NK cells are easily expandable and modifiable allogeneic effector cells, enhancing the versatility and simplicity of treatment while compensating for the weakened autoimmune cells in patients with advanced cancer. CAR-NK cells kill target cells through CAR-dependent and NK cell receptor-dependent mechanisms, eliminating tumor cells positive for tumor-associated antigens or expressing NK cell receptor ligands. Shenzhen Cell Valley will provide a full-process service from NK cell collection and transduction to expansion, with transduction efficiency of exogenous genes exceeding 50%, helping clients accelerate their research in the CAR-NK field.
