Multi-method Analysis of Calcium Localization in the Secretory Ameloblast
D. R. Eisenmann, S. Ashrafi, A. E. Zaki
X-ray micro-analysis and electron energy loss analysis were used to confirm cytochemical localization by potassium pyro-antimonate of calcium in secretory ameloblasts. Neither intercellular calcium concentration between ameloblasts nor over-all calcium levels of the enamel organ were lowered during a period of inhibition of enamel mineralization by injected fluoride. Calcium concentrations in mitochondria and secretory granules were reduced.
