Cell-based assays play a central role in the development of safe and effective cell therapies. They serve as methods for quantifying the potency of cell therapies, providing readouts for a broad spectrum of cell therapy characteristics, and are essential throughout the process from initial screening to safety and efficacy testing and dosage optimization1,2. Researchers employ a wide range of advanced cell-based assays in determining cell therapy characteristics, including growth assays, killing assays, metabolic profiling, xenograft models, and molecular profiling3–7.
