[Ultrastructural characteristics of the epithelial cells of the cortico-medullary transition layer in the mouse thymus].
The authors examined the fine structure of the epithelial cells, obtained from the cortico-medullary transition in the thymus of 4-months conventional mice Swiss, killed by decapitation. Apart from dark and bright epithelial cells, which formed cellular reticulum of the whole thymic lobule, they described three types of epithelial cells, characteristic of this area. These cells differed mainly by the character of their vascular components, whose richness and variety was combined with other cytologic signs of increased functional activity, manifested at various degree. The obtained results widened the picture of the cortico-medullary transition as an area, independently formed in other breeds of animals with data of a thymus similar to that of a mouse and were morphologic proof for the significance of its epithelial reticulum in the functional activity of the thymus.
