    Notes: Abstract. We investigated morphology, dynamics and origin of cells surrounding the mouth of Hydra vulgaris using the monoclonal antibody L96. This antibody recognises a one cell-thick ring of endodermal epithelial cells exactly at the boundary between endoderm (gastrodermis) and ectoderm (epidermis). L96+ cells can stretch considerably without any cell rupture during mouth opening. Thus, our data prove the existence of a distinct cell population defining hydra’s mouth. A model for mouth opening is proposed and the significance of L96+ cells for boundary formation between ectoderm and endoderm is discussed.

    Notes: Die Nematocyten (Nesselzellen) der Cnidaria (Nesseltiere) sind eine der komplexesten und rätselhaftesten aller tierischen Zellen. Ihr charakteristisches Organell, die Nesselkapsel (Nematocyste, Cnide), gehört zu den größten bekannten Sekretionsorganen, und ihre explosive Entladung ist einer der spektakulärsten Prozesse, den man auf Ebene einer Zelle beobachten kann. Tödliche Badeunfälle, die durch Kontakt mit manchen tropischen Würfelquallen hervorgerufen werden, zeigen auch die. Gefährlichkeit des Nesselgiftes. Die Aufklärung von Struktur und Funktion dieser Zellen stellt daher schon lange eine Herausforderung für Biologen und Biophysiker dar. Neue molekular- und zellbiologische Untersuchungen haben uns nun einem Verständnis dieser ungewöhnlichen Zellen näher gebracht.
