We developed a breast cancer-on-chip model with an integrated endothelial barrier that enables the transmigration of perfused immune cells, their infiltration into the tumor, and concomitant monitoring of cytokine release during perfused culture over a period of up to 8~days. Here, we exemplified its use for investigating CAR-T cell efficacy and the ability to control the immune reaction with a pharmacological on/off switch. Additionally, we integrated primary breast cancer organoids to study patient-specific CAR-T cell efficacy. The modular architecture of our tumor-on-chip paves the way for studying the role of other cell types in the TME and thus provides the potential for broad application in bench-to-bedside translation as well as acceleration of the preclinical development of CAR-T cell products.}, year = {2024}, journal = {Cell Stem Cell}, volume = {31}, pages = {989-1002.e9}, month = {2024-07-05}, issn = {1934-5909}, url = {https://www.sciencedirect.com/science/article/pii/S1934590924001450}, doi = {10.1016/j.stem.2024.04.018}, }
