Abstract

Electron probe microanalysis has revealed that vesicular or cisternal structures containing electron-dense material in frog ependymal glial cells contain deposits of calcium and phosphorus. The so-called "osmiophilic particles" in human astrocytes also contain calcium. It is suggested that these organelles are storage sites of calcium.
