[Spatial morphology of the mitochondria of the proximal and distal tubules of the kidney].
A new histological technique of block staining based on the use of a double lead and copper citrate is described in order to observe thick sections (0.5-1.5 micron) with a transmission electron microscope. With this technique, a network of mitochondrial with many morphological communications was seen in the epithelial cells of the proximal and distal convoluted tubules of the rat nephron. A new schematic view of the proximal and distal tubular cell is presented to illustrate the communications of the chondriome, which could become more or less accentuated following the functional status of the cell.
