Intermediate filaments belong to a large family of proteins which contribute to the formation of the cytoskeleton. The immunolocalization of cytoskeletal proteins has been used extensively in the diagnosis of various renal pathologies. The present study described the immunolocalization of the cytoskeletal proteins vimentin, desmin, smooth muscle ac...

The inner layer contained numerous smooth muscle cells, while the outer layer was predominately composed of dense irregular connective tissue (Fig. 1A). The kidney parenchyma was divided into an outer cortex and an inner medulla (Fig. 1A, B). Cortical and juxtamedullary nephrons were observed in the kidney. The renal corpuscles of ...

... of juxtamedullary nephrons were situated in the inner cortical region. The loops of Henle in cortical nephrons were short in contrast to the long loops of juxtamedullary nephrons, which extended into the medulla. The cortical region of the kidney contained renal corpuscles, proximal and distal convoluted tubules, as well as blood vessels (Fig. 1C, D). The renal corpuscles were composed of a glomerulus and glomerular capsule (Bowman's capsule). The glomerulus was formed by glomerular capillaries and mesangial cells (Fig. 1C). The glomerular capsule was formed by an inner visceral and an outer parietal layer. The visceral layer was composed of podocytes, which contained large, ...
