Alveolar type II epithelial cells in A) the control lungs, B) untreated lungs subjected to I/R and C) surfactant treated lungs subjected to I/R. Note the dilations of the endoplasmic reticulum (arrows) in the untreated I/R group and the large amount of small lamellar bodies (arrows) in the surfactant treated group. The mitochondria (M) had a more electron lucent matrix in the untreated I/R group than in the other two groups. Lb = lamellar bodies; Cap = capillary lumen; Alv = alveolar lumen; Surf = surfactant; N = Nucleus.
