Camping-Neulinge wundern sich beim Auffalten eines Zeltes, dass die große Zeltplane in einen fußballgroßen Sack passt. Biologen staunen über Ähnliches: Wenn sich eine Zelle teilt, wächst die Fläche der Zellmembran. Auch wenn im Innern der Zelle Stoffe von einem Organell zum anderen gebracht werden, bilden sich membranumschlossene Transportkügelchen, so genannte Vesikel. Um Membranen schnell zur Verfügung stellen zu können, speichern Zellen in ihrem Innern Membranfläche in Form von Nanoröhrchen, schlauchförmigen Einstülpungen der Zellmembran - ähnlich wie die zusammengefaltete Zeltplane. Forscher des Max-Planck-Institutes für Kolloid- und Grenzflächenforschung in Potsdam haben nun einen Mechanismus entdeckt, wie die Zelle stabile Membran-Nanoröhrchen bildet.
