Summary This study describes the distribution of vimentin, desmin, smooth muscle actin ( SMA ) and laminin in the oviduct of the laying domestic fowl. Vimentin immunostaining was localised in the luminal epithelium of the infundibulum, magnum, magnum–isthmus junction and isthmus. The luminal epithelium of the shell gland regions displayed weak vimentin immunostaining. Vimentin immunostaining was demonstrated in the glandular grooves of the tubular infundibular region. In contrast, gland cells in the magnum, isthmus and shell gland regions were vimentin immunonegative. Fibroblasts and vascular endothelial cells in the lamina propria of the oviductal regions studied exhibited vimentin immunostaining. Strong desmin and SMA immunostaining were present in the smooth muscle cells of the tunica muscularis and vascular tunica media. In this study, basement membranes underlying the luminal and glandular epithelia were immunopositive for laminin. In addition, basement membranes associated with smooth muscle cells exhibited laminin immunostaining. The results of the study indicate that the immunolocalisation of desmin, SMA and laminin in the oviduct of the domestic fowl is similar to that in the mammalian uterus. The immunolocalisation of vimentin in the domestic fowl varies depending on the oviductal region.
