Cytokine-induced killer (CIK) cells, a subset of effector natural killer T cells characterized by CD3+CD56+ markers, hold promise as a cancer immunotherapy. These cells exhibit potent, MHC-independent anti-tumor activity and can be easily expanded in vitro from peripheral blood mononuclear cells. However, their clinical efficacy is hindered by factors like the immunosuppressive tumor microenvironment, short cell persistence, and variable cytotoxicity. To maximize their therapeutic potential, ongoing research is dedicated to developing innovative strategies to address these limitations and broaden the application of CIK cell therapy.

Genetically modified CIK (GM-CIK) cells represent a promising approach in cancer immunotherapy. At Creative Biolabs, we offer comprehensive GM-CIK development services to advance your research and develop innovative therapies. Our services encompass multiple selective CIK genetic-engineering strategies, such as CAR-CIK cell engineering, cytokine-engineered CIK cells, CIK cells equipped with safety switches, and DC-CIK co-culture. By implementing specific genetic modifications, we are capable of enhancing CIK cells' anti-tumor activity, target specificity, and persistence. Our rigorous quality control system ensures the safety and efficacy of our GM-CIK products. Leveraging our advanced platform and experienced team, we are committed to delivering high-quality CIK products that meet your research needs.
By transferring tumor-specific antigens into CIK cells, we create CAR-CIK cells with significantly enhanced tumor-killing efficacy and specificity. Our extensive tumor-specific antigen library allows us to design a variety of unique CARs, tailoring them to target specific tumor antigens and optimize their therapeutic potential.
Modified Cytokine Receptor-CIK Development Service
In addition to CAR-CIK cell engineering, we are capable of transferring modified cytokine receptors into CIK cells. This genetic modification enhances CIK cell proliferation, activation, and cytotoxicity, resulting in improved anti-tumor activity and specificity. By precisely engineering these receptors, we can fine-tune CIK cell responses and optimize their therapeutic potential.
CIK Incorporating Safety Switch Development Service
Creative Biolabs provides a CIK incorporating safety switch development service to incorporate innovative safety switches (suicide genes system) into CIK cells. These safeguards allow for precise control over CIK cell proliferation. If necessary, the safety switches can be activated to eliminate the CIK cells, minimizing potential side effects.
Dendritic Cell (DC)-CIK Development Service
In addition, we also offer comprehensive DC-CIK development services to advance cancer immunotherapy. By co-culturing dendritic cells (DCs) and cytokine-induced killer (CIK) cells, we harness their synergistic effects to enhance anti-tumor activity.
Please don't hesitate to get in touch with us for more detailed information about our genetically-modified CIK development services.
