    Scanning electron microscopic observations of the basal surface of the human oral mucosa and squamous cell carcinoma (1993)
    Springer
    Medical molecular morphology 26 (1993), S. 227-229

    Notes: Abstract The basal surface of epithelial cells in the normal oral mucosa and cancer lesions were investigated by scanning electron microscopy. The basal lamina and collagen fibers having been completely removed by strong alkali digestion, the true basal surfaces of the epithelium and cancer lesions were demonstrated in three dimensions. Visible on the outer surface of the nest of cancer cells was a flowerlike structure, presumably the connecting portion of the neighboring cancer nest.

    Ultrastructure of the basal surface of the rat corneal epithelium (1994)
    Springer
    Medical molecular morphology 27 (1994), S. 159-164

    ISSN: 1860-1499
    Keywords: NaOH digestion method ; Basal epithelial surface ; Calcium deposits ; Rat ; Scanning electron microscopy (SEM)

    Notes: Abstract Basal surfaces of the rat corneal epithelium were studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The epithelium was dissociated from the underlying stroma by dissolving the basal lamina with NaOH, and its basal surface was observed by SEM. Depressions, produced by the indentations of the plasma membrane, were present on the basal cell surfaces in rats which were 15 and 18 months old. TEM observations clarified that electron-dense deposits, presumably containing calcium, were located in the depressions. These depressions also accompanied the thickened basal lamina.

    A vascular network closely linked to the epithelium of the urinary bladder of the rat (1991)
    Springer
    Cell & tissue research 263 (1991), S. 137-143 
    Details
    ISSN: 1432-0878
    Keywords: Urinary bladder ; Capillary ; Urothelium ; Vascularization ; Rat (Sprague-Dawley)

    Notes: Summary Scanning electron microscopy was used on the mucosa of the rat urinary bladder after digestion with strong alkali and microdissection. The underside of the epithelium (and the plane of the epithelium-tunica propria interface) is not smooth but is scored by grooves-10 μm wide and 3–4 μm deep—connected into a fine mesh. A net of blood capillaries located in the uppermost part of the tunica propria occupies these grooves. They measure 3–9 μm in diameter, are separated from the epithelium by a gap of 0.3 μm, often show fenestrations, and are accompanied by numerous and extensive pericytes and by some fibroblasts. We discuss these observations in the light of current knowledge of blood flow in the bladder, contraction and distension of the bladder wall and formation of mucosal folds, transport of solutes through the epithelium, and plasma extravasation from mucosal blood vessels in neurogenic inflammation.

    An application of rapid freezing, freeze substitution-fixation for scanning electron microscopy (1985)

    Notes: A combined technique of the rapid freezing, freeze substitution-fixation method and the osmium-DMSO-osmium method was devised. By this combined method we clearly observed the architecture of intracellular components in three dimensions. Morphological characteristics were generally similar to those of tissue prepared by the osmium-DMSO-osmium method but different in some respects. Mucigen droplets in intestinal goblet cells, for example, appeared as separated spheres, while in specimens prepared by chemical fixation they were observed as a mass of fused droplets. In the Golgi complex, all cisternae were extremely flat, although they usually dilated on the cis side after chemical fixation. Particles on the mitochondrial tubules of liver cells were well distinguished. They were mushroom shaped, as are those observed by negative staining. The combined method, that is, the rapid freezing, osmium-DMSO-osmium method, is thought to be effective for studying the true structure of intracellular components by scanning electron microscopy.
