Intravital microscopy analysis. Representative one-photon intravital microscopy videos of livers from two independent mixed BM chimera mice infected with mCMV and analyzed 16 h after infection, as detailed in Fig. 8. Playback speed 4 fps (frames per second). Ccl3 producing cells expressing tdTomato are shown in red, Ccl3 recipient cells are shown in green (Venus+). Chimeric cells were identified with CD45.1+ signal in blue. Data is representative of two independent experiments (n = 8 mice).
