Stammzellen unter Zugzwang

(PresseBox) (Köln, )
Ein Team von Wissenschaftler/innen um Sara Wickström, Arbeitsgruppenleiterin am CECAD, dem Exzellenzcluster für die Erforschung altersassoziierter Erkrankungen an der Universität zu Köln, hat neue Einblicke gewonnen, wie Stammzellen fühlen und auf externe mechanische Reize reagieren. Dies geschieht durch eine Veränderung der DNA im Zellkern und einer daraus folgenden veränderten Expression von Genen, die für die Differenzierung der Stammzellen benötigt werden.

Alle Zellen haben den identischen genetischen Code, egal ob es sich um Haut- oder Gehirnzellen handelt. Diese Zellen sind aber völlig verschiedenen Umgebungen und mechanischen Belastungen ausgesetzt. Gehirnzellen sind zum Beispiel sehr weich, Knochen hingegen extrem hart.
