NYU Engineers Develop First Immunocompetent Leukemia-on-a-Chip Device to Advance CAR-T Cell Therapy Testing
- Researchers from NYU Tandon School of Engineering and University of Pennsylvania have created the first microscope slide-sized "leukemia-on-a-chip" device that combines bone marrow structure with a functioning human immune system.
- The device enables real-time observation of CAR-T cell dynamics in an authentic microenvironment, revealing previously unseen interactions including a "bystander effect" where engineered cells stimulate non-targeted immune cells.
- The platform can be assembled within half a day compared to months for animal models, opening possibilities for personalized medicine applications where patient-specific samples can be tested against multiple CAR-T cell designs.
- Fourth-generation CAR-T cells demonstrated superior performance at lower dosages within the chip environment, suggesting potential for optimizing dose regimens while reducing toxic side effects.
