Ablation of Pericyte-Like Cells in Lungs by Oropharyngeal Aspiration of Diphtheria Toxin.

abstract：:Previously it was reported that hyperoxia induced death of the human lung adenocarcinoma cell line (A549 cells) by necrosis, not by apoptosis. This study examined proliferation and death of untransformed human small airway epithelial (SAE) cells in normoxia or hyperoxia in comparison with A549 cells. We tested the hyp...
