title: Selective electronmicroscopical contrast of the ring canals joining germ cells by ethanolic phosphotungstic acid and uranyl-EDTA-lead.
abstract: The edge of ring canals joining germ cells in mouse testis show a high and selective electronmicroscopical contrast after application of ethanolic phosphotungstic acid and uranyl-EDTA-lead. The contrasting reaction of this fibrous structure, which originates from the contractile ring during previous cytokinesis, is briefly discussed.
