This is particularly important for immunological studies, as species‐specific differences in cytokine signaling, antigen presentation, and T‐cell receptor interactions can significantly impact experimental outcomes.[34] By incorporating human cells cultured under physiologically relevant conditions, our microfluidic IAC system provides a promising platform for evaluating CAR T‐cell interactions with the tumor microenvironment under near‐physiological conditions. This evidence concerns the gene TBXT and neoplasm.
