Micromorphological characteristics of hepatic sinusoidal endothelial cells and their basal laminae in five different animal species.
The micromorphological characteristics of hepatic sinusoidal endothelial cells and their basal laminae in five different animal species (cow, sheep, guinea pig, pig, and dog) were studied by electron microscopy. Using transmission electron microscopy, a prominent basal lamina was seen only in cow and sheep. In pig and guinea pig, no prominent basal lamina was evident. Basal lamina-like material was occasionally found in dog. Immunohistochemically, basal lamina was found in cow, sheep, and dog. Using scanning electron microscopy, the size of endothelial fenestrae differed between species. These results may suggest that variation of endothelia and their basal laminae of different species is related to differences in nourishment.
