Figure 2From: Environmental control of invasiveness and metastatic dissemination of tumor cells: the role of tumor cell-host cell interactionsChange in lung-colonizing potential of B16 murine melanoma cells upon stimulation by TAM. Surface colonies (A, B) and H&E-stained sections (C, D) of lungs collected from syngeneic animals injected with un-stimulated melanoma cells (A, C) or tumor cells stimulated by macrophages (B, D). See the high number of metastatic lesions in lungs from animal injected with macrophage-promoted tumor cells.Back to article page
