Summary

Chondrocytes of the rat epiglottis contain large amounts of glycogen and lipids, which often make the cells resemble fat cells. The content of lipids is interpreted as being related to the function of the cells. The membranes of some of the large vacuoles are stained with ruthenium red. The cells give rise to long cytoplasmic processes. As in hyaline cartilage the intercellular substance consists of a fine network containing proteoglycan granules together with thicker cross striated fibers. Furthermore elastic fibers are found, consisting of amorphous and microfibrillar parts. In the matrix, both lysosome-like granules and more or less empty vesicles are observed. Accumulations of a finely particulate electron dense material and of a translucent amorphous material containing membrane bound granules are found in some lacunae situated in the outer part of the cartilage. These accumulations are possibly related to the development of collagenous and elastic fibers.
