- 論文の詳細を見る
Fluorescence, light, and electron microscopic observations of the carotid labyrinth of the newt Cynops pyrrhogaster showed the presence of glomus cells in the intervascular stroma of the labyrinth. These cells contain many dense-cored vesicles (60nm-100nm in diameter) and their ultrastructure was similar to that of glomus cells reported in many other animal species. In some glomus cells, there were intranuclear inclusion bodies (0.1-0.3μm in diameter), and long processes were in close contact with endothelial cells or with pericytes, which have not been reported in the carotid labyrinth so far. Two types of synapses (efferent and afferent) were found on the glomus cell surfaces. So-called reciprocal synapses were also found. On the basis of these findings, I conclude that the newt glomus cells may have a secretory as well as a chemoreceptor function.
