Zusammenfassung
Die Verff. stellten bei ihren elektronenmikroskopischen Untersuchungen Veränderungen der Basalmembran (Polystratifizierung oder Verbreiterung) in drei Zonen des menschlichen Haarfollikels fest, und zwar im oberen Teil der äußeren Mittelscheide, an der Papillenspitze und in der Papille.
Bemerkenswert ist das Vorhandensein eines Verbindungsnetzes zwischen Capillaren, Cutiskomponenten und Epithelzellen des Follikels innerhalb der Papille. Das Netz besteht aus polystratifizierten und retikulären Strukturen, ähnlich denen der Grenzmembran von Epithelien und Endothelien. Diese besonderen Aspekte der Basalmembran werden unter Berücksichtigung der neuesten Literatur besprochen.
Summary
Changes in the basement membrane (multistratification or thickening) have been observed in three zones of the human hair follicle: in the upper portion of the outer root sheath, around the tip of the papilla and within the papilla. The most striking finding is the presence within the papilla of a connecting system between capillaries, components of the dermis and epithelial cells of the follicle, consisting of multilayered, reticular structures in all respects similar to the limiting membranes of epithelium and endotheliu. These peculiar features of the basement membrane are discussed in the light of the latest data in the literature.
