Mast cells within the tumor microenvironment have controversial roles. Here, the authors show, using genetic mouse models, that in gastric cancer, mast cells at the periphery of the tumors are activated via cancer cell produced-IL33 and promote tumorigenesis by recruiting macrophages within the tumors.
