In vivo and in vitro study of59Fe uptake in developing rat molars

Abstract
Bawden, J.W., Wennberg, A. Hammarström, L. In vivo and in vitro study of 5 9Fe uptake in developing rat molars. Autoradiographic methods were used to study 59Fe uptake in vivo in mineralizing tissues of young rats. Localization of 5 9Fe was observed in the ameloblastic layer of molars. In vitro studies were performed which demonstrated that 5 9Fe uptake in developing rat molar enamel was limited by the metabolic activity of the cells of the enamel organ.
