Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with one of the poorest prognosis among all malignancies. The initiation and evolution of this kind of tumor depends on a complex interaction between cancer cells and the tumor microenvironment (TME). In an elegant study, Steins et al  used a combination of relevant disease models to show that mesenchymal subtype of PDAC shows a distinct deactivation of stellate cells in a CSF1-dependent fashion. This study shedding light on a new role for the stroma driving an aggressive PDAC subtypes shifts the current paradigm for the requirement of an activated TME to regulate PDAC growth and maintenance.
