Abstract: | Summary The middle ear capillaries of the guinea pig have fenestrated endothelium, and the intercellular clefts are closed by tight junctions. Intracardially injected horseradish peroxidase penetrates the fenestrae of the endothelium and gains access to the extra-cellular space beneath the epithelium, and the intercellular clefts of the epithelium. |
