Intravital bone marrow imaging of lymphoma-bearing mice treated with control T cells. C57BL/6 mice were sublethally irradiated and injected with Eμ-myc-DEVD tumor cells 7 d before treating them with untransduced GFP⁺ activated CD8⁺ T cells (control cells). Mice were subjected to intravital bone marrow imaging 40 h after T cell transfer. Live tumor cells appear in gray, apoptotic tumor cells in blue, and T cells in green. Scale bar represents 20 μm. Total duration = 27 min.
