Tumor-killing cells with on-demand self-destruct. 

Scientists engineered tumor cells to secrete a molecule that causes death of the main tumor they came from, but not the engineered cells. Then, they triggered self-destruct of the engineered cells with a targeted drug. “The authors then tested the efficacy and safety of this method in mouse models of primary, recurrent, and metastatic tumors.” The link is to the raw publication in Science Translational Medicine. learn more
