In menschlichen Zellen finden sich stammesgeschichtlich sehr alte Funktionseinheiten, die als Centriolen bezeichnet werden. Sie nehmen eine wichtige Rolle bei der Zellteilung wahr und bilden das Fundament für feinste Oberflächenstrukturen, mit denen Zellen ihre Umwelt wahrnehmen, miteinander kommunizieren oder sich fortbewegen. Während ihre Funktion bereits gut beschrieben ist, sind die Mechanismen, die zur Bildung der Centriolen führen, seit Jahren Gegenstand einer offenen Frage. Im Fokus steht die Architektur der Centriolen, die durch eine mysteriöse Neuner-Symmetrie charakterisiert ist.
