From: Quantification of protein Z expression in lung adenocarcinoma tissues and cells
Representative images from immunohistochemical staining. In lung adenocarcinoma tissue (a), an increase in PZ staining (brown) is observed. The black arrow indicates the cytoplasmic expression of PZ, while the red arrow and yellow arrow indicates the presence of PZ protein in macrophages and endothelial cells, respectively. Scale bar 50 μm. b PZ protein was not expressed in the cytoplasm of cells in healthy lung tissue. The positively stained cells are macrophages (red arrow) and endothelial cells (yellow arrow). Scale bar 50 μm
