Der Zebrafisch, ein kleiner Süßwasserfisch, verdankt seinen Namen einem auffallenden Muster von blauen und goldenen Längsstreifen. Drei Typen von Pigmentzellen, schwarze, silbern reflektierende, und gelbe, tauchen während des Wachstums in der Haut von jungen Fischen auf und ordnen sich in einem mehrschichtigen Mosaik an, welches das charakteristische Farbmuster ausbildet. Bisher wusste man, dass alle drei Pigmentzelltypen miteinander wechselwirken müssen, um ordentliche Streifen zu entwickeln. Die Herkunft der Zellen im Embryo, die dann später das Muster des erwachsenen Fisches bilden, blieb jedoch ein Rätsel. Wissenschaftler am Max-Planck-Institut für Entwicklungsbiologie in Tübingen haben nun entdeckt, wo diese Zellen entstehen und wie sie jpi Bfgup-Azjwxg xolrag.
