Abstract
A novel microfluidic approach specifically designed to engineer human primary T-lymphocytes effectively with high scalability while maintaining cell functionality is reported. The system employs a unique cell elongation-restoration phenomenon called “cell stretching,” which enables highly effective intracellular delivery of external cargos into cells. Vortical recirculation flows are exerted where cells are hydrodynamically elongated and restored, resulting in effective permeabilization of the cellular membrane. Using the platform, highly efficient (>90%), low-material-cost (<$1), minimally invasive, and high-throughput (106 cells/min) delivery of various cargos into human primary T-cells was achieved, demonstrating the practical utility for chimeric antigen receptor (CAR) T-cell-based cancer immunotherapy.
