Figure 2
Lung morphology of BM chimera mice. Representative lung sections from GFP BM chimera mice were examined on day 28 (a and c) and day 56 (b and d) after BMT, by light microscopy (a and b, H&E-stained sections) and fluorescence microscopy (c and d). At day 28 after BMT (a), lungs from GFP BM chimera mice revealed essentially normal lung architecture and no evidence of pneumonitis. At day 56 after BMT (b), the lungs also appeared essentially normal, except for a few scattered inflammatory cells. Only a few GFP⁺ cells were present in lung sections on both days 28 (c) and 56 (d) after BMT. Insets in c and d showed light-microscopic images of the unstained sections used for fluorescence microscopy. All images were photographed at ×100.
