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.<p><b>Copyright information:</b></p><p>Taken from "Exogenous surfactant application in a rat lung ischemia reperfusion injury model: effects on edema formation and alveolar type II cells"</p><p>http://respiratory-research.com/content/9/1/5</p><p>Respiratory Research 2008;9(1):5-5.</p><p>Published online 18 Jan 2008</p><p>PMCID:PMC2265285.</p><p>
