Eine kleine Gruppe von Stammzellen im Knochenmark verschläft fast das ganze Leben. Erst Verletzungen oder Blutverlust erwecken sie zur Aktivität: Unverzüglich beginnen sie mit der Zellteilung, bis der Verlust an Blutzellen wieder ausgeglichen ist. Die Möglichkeit, diese schlafenden Stammzellen gezielt aufzuwecken, eröffnet neue Perspektiven für die Krebstherapie, wie Wissenschaftler aus dem Deutschen Krebsforschungszentrum sowie aus der Ecole Polytechnique Fédérale und dem Ludwig Institute for Cancer Research in Lausanne in den neuesten Ausgaben der Zeitschriften "CELL" und "CELL Stem Cell" veröffentlichen.
Viele spezialisierte Zellen, etwa in der Haut, Darmschleimhaut oder im Blut, haben nur eine Lebensspanne von wenigen Tagen.
