α 5 was expressed by and ATII cells Clara cells at PN1. Staining for TTF-1 (A) and α5 (B) in serial sections from PN1 mouse lung revealed α5 is co-expressed with TTF-1 in many ATII cells, but not all (arrows). Staining for CCSP (C) and α5 (D) also identified consistent α5 expression in bronchiolar epithelium at PN1 (arrows). All images are at 80× original magnification.
