Abstract
Four rhesus monkey pituitary glands were examined by transmission electron microscopy. Three types of intercellular junctions, desmosomes, hemidesmosomes and zonula adherens-type junctions, were observed between adjacent granular cells, folliculo-stellate cells, and joining a folliculostellate cell with a granular cell. Desmosomes were most commonly observed between granular cells while the zonula adherens-type junctions were generally found between the folliculo-stellate cells.
