Zusammenfassung

Innerhalb der verhornten Zellen, die von 5 verschiedenen Quellen stammten, wurden häufig Inseln mit dreifach geschichteten Zellmembranen gefunden. Sie entstanden aus Falten der Protoplasmamembran, nachdem die der Membran anliegenden Körnchen abgestoßen worden waren, oder aus Falten der Protoplasmamembran infolge von Zelltrocknung und Schrumpfung. Das verdickte Grenzband wurde nicht auf diesen intracellulären Inseln der Protoplasmamembran gebildet.

Summary

Within the keratinized cells from five different sources, the trilaminar plasma membranes were commonly found. They have derived from the invaginated plasma membrane formed when the membrane-coating granules were discharged, or from infolded plasma membrane due to cellular dehydration and shrinkage. The marginal band was not formed upon these intracellular plasma membranes.
