Mimicking breast cancer tissue—3D bioprinted models in accurate drug sensitivity tests

VIEW, EarlyView.
Three‐dimensional (3D) bioprinted tumor models provide a novel method for studying drug sensitivity. This study compares drug response patterns of 3D bioprinted breast cancer models with xenografts and syngeneic tumors, showing that bioprinted models more accurately reflect the drug sensitivity and tissue heterogeneity of syngeneic tumor model.
