Die Mechanik der Zelle

Untersuchung einfacher Modellzellen klärt Mechanismen der Verformung

(PresseBox) (München, )
Lebende Zellen müssen sich aktiv verformen können, sonst könnten sie sich beispielsweise nicht teilen. An der Technischen Universität München (TUM) haben der Biophysiker Professor Andreas Bausch und sein Team ein synthetisches Zellmodell entwickelt, um grundlegende Gesetzmäßigkeiten dieser Zellmechanik zu erforschen.

Eine lebende Zelle hat kein entspanntes Dasein: Ständig muss sie ihre Gestalt anpassen. Wenn sie sich teilt, muss sie ihre gesamte Form massiv umbauen. Wenn sie Stoffe aufnimmt, muss sie ihre äußere Membranhülle stark verformen. Und wenn sie auf Wanderschaft geht, muss sie zunächst einmal entscheiden, wo vorne und wo hinten ist, dann ihre eingebauten molekularen Motoren anwerfen und so lkv Xawnsyfttjff xe Mjbg jovhpg.
