The understanding of the mechanisms underlying the ability of disseminated tumor cells (DTCs) to form metastasis is incomplete. Here, by using high-resolution intravital imaging of the murine lung to track the fate of breast-derived DTCs, the authors show that macrophages within the primary tumor induce a pro-dissemination and pro-dormancy phenotype in tumor cells, favouring their extravasation in the lung.
