Abstract

Understanding the mechanisms of injury in respiratory distress syndrome may improve treatment methods. We hypothesize that mechanical stresses associated with airway reopening may contribute to the pathology of RDS by altering the biochemical activities of the epithelium. We found that L2 cells produce mitogens and/or other compounds in vitro, which stimulate fibroblast proliferation when exposed to a short static transmural pressure but not oscillatory pressures
