||P.S47 right column 3rd paragraph: "Vascular endothelium in general has an immense capacity for regeneration after injury. This holds for the pulmonary endothelium, e.g., during recovery from oxygen injury when as much as 8% of all pulmonary cells are actively synthesizing DNA at any one time, at least 50% of these cells are endothelial (primary sources)."
