Identification of MFAP5⁺ cells in human distal lung tissue. (A–D) Images of serial sections of normal human lungs stained with hematoxylin and eosin (H&E, left panel) and probed by RNA in situ hybridization for MFAP5 (right panel). The scale bar is 100 µm. Areas inside rectangles (dashed) are magnified in lower panels. All images in the figure are from the same individual. MFAP5⁺ cells in adventitia of larger blood vessels (A,B), small blood vessel (C) and interlobular septum (D). adv adventitia, med media, lu lumen, sep interlobular septum.
