Cover: Immunofluorescent photomicrograph of tenascin (red) and phospho-Smad2 (green) immunoreactivity (left panel) and HSP47 (red) and phospho-Smad2(green) immunoreactivity (right panel) in the airway mucosa. Colocalization of both proteins results in the appearance of a yellow-orange signal. Tn, tenascin; bv, blood vessel; L, lumen. Cell localization was on the basis of morphology: FX, fibroblast; Epi, epithelium. For more information, see article by Phipps and colleagues, beginning on page 626.
