[Ultrastructure of the interstitial cells of the rat kidney medulla].
Ultrastructure of the interstitial cells of the internal zone of the medulla of kidney in rats is detailly described. Electronmicroscopical feature of these cells may be connected with several functions i.e. urine-concentration, electrolyte-transport, production of intercellular matrix and vasodepressor-lipids. Ultrastructural picture of production and elimination of lipid droplets is not yet cleared out. Authors stress, that for the appropriate fixation of zones of different ion-concentration of the medulla special fixatives of an appropriate osmotic pressure are necessary.
