Immunohistochemical characterisation of CCL21 expression. (AD) are serial sections stained for podoplanin (A and C) and CCL21 (B and D). CCL21 was exclusively expressed in the podoplanin+ existing lymphatic vessels in the HP sections (arrows in A and B). Scale bar, 100 µm. In IPF, CCL21 expression was detectable in the podoplanin+ newly formed lymphatic vessels in the massive fibrotic lesions HP (arrows in D). Scale bar, 100 µm. All sections were counterstained by resorcin-fuchsin and haematoxylin.
