Summary

Epidermal cell suspensions derived from keratotomed samples of normal human skin have been studied by light microscopy and by scanning and transmission electron microscope techniques. The method allows detailed inspection of the keratinocyte membranes. However, the trypsin used to obtain the suspensions limits the usefulness of the technique as some of the features observed — including invagination of desmosomes, vacuolation, and redistribution of tonofibrils — may be attributable to this proteolytic enzyme.

Zusammenfassung

Die epidermale Zellsuspensionen, die mit dem Keratom von menschlicher Haut gewonnen wurden, konnten lichtmikroskopisch und ruch Scanning und Transmissionenelektronenmikroskopie untersucht werden. Diese Methode erlaubt eine detaillierte Analyse der Keratinocytenmembran, jedoch wird die Aussage der mit Trypsin behandelten Suspensionen durch Effekte beeinträchtigt, die wie Invagination der Desmosomen, Vakuolisierung und Verteilung der Tonofibrilen der proteolytischen Wirkung dieses Enzyms zugeschrieben werden müssen.
