Figure 2

Representative micrograph demonstrating typical features of injury observed in the I/R group. The AE2 cell contains Lb, M, ER and N. A multi-vesicular body (MV) is visible. With respect to AE2 cell ultrastructure, no obvious differences can be seen compared to the AE2 cell shown in Figure 1. The alveolar space is filled with alveolar edema (ed) and erythrocytes (ery). The blood-air barrier is damaged as indicated by the fragmented alveolar epithelial lining (*) including areas with denuded basement membrane. Scale bar: 5 μm.
