Although the importance of NK cells as immune effector cells in controlling growth and metastatic dissemination of tumor cells has been widely recognized, it is unclear whether NK cells in different organs similarly control tumor cell growth and metastasis. In the present study, we established a bioluminescent imaging model of mouse T cell lymphoma cells, which are highly susceptive to NK cell-dependent immune-surveillance, to monitor the dissemination of lymphoma cells using an in vivo imaging system. The use of this model is expected to be a highly sensitive method to examine the role of NK cells in controlling lymphoma dissemination in a variety of tissues.
