Der Transkriptionsfaktor Nanog spielt eine entscheidende Rolle bei der Selbsterneuerung von Stammzellen. Unklar war bisher, wie seine Menge in den Zellen geregelt wird. Forscher des Helmholtz Zentrums München und der Technischen Universität München berichten nun gemeinsam mit Kollegen der ETH Zürich in 'Cell Systems': je mehr Nanog vorhanden ist, desto weniger wird nachproduziert.
Das Protein Nanog* ist jedem Stammzellforscher ein Begriff, denn es sorgt dafür, dass sich diese Alleskönner immer wieder erneuern. Kontrovers diskutiert wurde bis jetzt, wie die Menge an Nanog in der Zelle kontrolliert wird.
