Fig. 6From: Cellular and acellular ex vivo lung perfusion preserve functional lung ultrastructure in a large animal model: a stereological studyStereological estimation of alveolar epithelial surface (a), endothelial surface (b) and blood-air barrier thickness (bab) (c). Group differences were not statistically significant (alveolar epithelial surface p = 0.103; endothelial surface p = 0.990; bab thickness p = 0.075).
