Front Cover: Vascularized tumor-on-a-chip platforms replicate human tumor microenvironments by integrating perfusable vessels and stromal elements in microfluidic systems. These models enable dynamic assessment of drug delivery and therapeutic response under physiologically relevant flow, offering enhanced predictive value for cancer treatment. In the review 10.1002/mabi.202500240, Hyelim Kim, Seung-Woo Cho, and Hong Nam Kim highlight recent advances and future opportunities in precision oncology using such engineered systems.
