title: [Immunomorphologic study of vertebrate renal glomerula using antibodies to intermediate filament proteins].
abstract: A comparative immunomorphologic study was carried out on cryostate sections of renal tissue of plaice (Pleuronectes platessa L.) and rat, using specific antibodies against the proteins of intermediate filaments--cytokeratins and vimentin. No cytokeratins were revealed in cells of renal glomerula in both the animals under investigation. Indirect immunofluorescence of the polyclonal serum against vimentin showed brightly coloured capillaries of the renal glomerula of plaice and weakly coloured ones of rat. At the same time cells of parietal epithelium of the Bowman capsule showed trace or negative reaction. The electron microscopic control revealed a powerful development of intermediate filament system in the podocyte cytoplasm of plaice, and a dense microfilament network and plural bundles of microtubules in the podocyte cytoplasm of rats. Problems of conservatism of the vimentin intermediate filaments in the evolution are discussed in addition to the present theories of the origin and development of renal glomerula of the vertebrates.
