The immunohistochemical distribution of phosphatidylglucoside (PhGlc) in organs obtained from human autopsy cases was investigated using the DIM21 antibody. Immunohistochemical staining was performed on formaline-fixed, paraffin-embedded sections using the simple stain peroxidase method. The sections were then subjected to antigen retrieval by microwave irradiation in citrate buffer. PhGlc expression was observed in not only the epithelial but also the non-epithelial components of several visceral organs. Squamous and glandular epithelial cells were positive for PhGlc in several organs. The surface areas of the epithelium, particularly the squamous epithelium, were positive. Mesothelial cells were also positive in some organs. Endothelial cells, polymorphonuclear (PMN) cells are positive in several organs. Macrophage is positive in many organs. Epithelial cells of the gallbladder were positive, however, the intrahepatic bile ducts were not positive. In the brain tissue, astroglial cells, the chorioide plexus, the pituitary gland, and ependymal cells were positive. Further investigation is indispensable in order to establish a relationship between cell differentiation and PhGlc expression.
