Structural differences in podocyte slit diaphragm. An ultrastructural model of slit diaphragm was proposed in three kinds of eucoelomates on the basis of previous research using en bloc staining with tannic acid (Boer and Sminia 1976; Rodewald and Karnovsky 1974; Schaffner and Rodewald 1978). Yellow Framework of slit diaphragm, white interstices, which is the passage for primary urine. These models illustrate the wide structural differences in the podocyte slit diaphragms among metazoan species (color figure online)
