FIG. 4.

Representative bronchoscopic images from each experimental group at the four bronchoscopy time points (3, 6, 9, and 12 weeks). The most common type of stenosis observed was side-to-side narrowing that occurred in 84% of total subjects with stenosis. Note that the photograph orientation is such that the scaffold is at the top of the photograph in each panel. *Bronchoscopy in the Scaffold only group was performed at week 7 and 10, instead of week 6 and 9.
