Fig. 7
Electron microscopic appearance of type II cells and lamellar bodies in Ad-Rab38-infected LEC rat lungs. a Ultra-thin sections (60 nm-thick) prepared from the left lungs were examined using a transmission electron microscope, and more than 25 fields were randomly photographed at a magnification of × 6,000. Star (*) indicates lamellar body. Bar: 6.6 μm. b Using ~25 electron microscopic photographs per experimental group, the areas of cells and lamellar bodies were quantified by an area-calculating software, and the numbers of lamellar bodies per single cell were counted. *P < 0.05, **P < 0.01, ***P < 0.001
