Summary
Intracellular cilia (single cilia) have been observed within basal keratinocytes and melanocytes of human epidermis in clinically normal skin and in several skin diseases.
In transverse sections of cilia a central pair of microtubules characteristic of motile flagella is missing in the axoneme of the ciliary stalk. Thus by their 9 + 0 pattern of microtubule arrangement, intracellular cilia belong to the modified type of cilia. Ultrastructure and intrinsic features of intracellular cilia are discussed with reference to their possible function in epidermal cells.
Zusammenfassung
Intracelluläre Geißeln wurden innerhalb der menschlichen Epidermis an klinisch normaler Haut und bei verschiedenen Hauterkrankungen in Basalzellen und Melanocyten beobachtet.
Die Anordnung der Mikrotubuli des Geißelzylinders entspricht mit einem 9 + 0-Muster dem Typ modifizierter Geißeln, die als sog. single cilia für zahlreiche Gewebetypen belegt sind. Aufbau und Feinstruktur der Geißeln werden beschrieben und mögliche Funktionen im Rahmen der Literatur diskutiert.
