On the basis of specific immunohistochemical staining for vimentin and cytokeratin, we conclude that in the mature placenta of the spotted hyena the interhemal membrane is haemomonochorial rather than endotheliochorial, as in other carnivores. We concur that the intrasyncytial laminae are remnants of the maternal endothelial basal lamina.
