Fig. 4From: Reduced receptor for advanced glycation end products is associated with α-SMA expression in patients with idiopathic pulmonary fibrosis and miceRAGE and α-SMA expression are differentially regulated in lung tissue of IPF patients. The represented images showed RAGE expression and collagen accumulation of IPF patient lung tissue. a H&E staining images of IPF patient lung tissue showed architecture damages. b Expression of RAGE and α-SMA were stained by immunohistochemistry. Green arrows were represented RAGE overexpression and Red arrows were represented α-SMA overexpression. a Scale bar: 50-μm; b Scale bar: 200-μmBack to article page
