Blutstammzellen bilden das Reservoir für die kontinuierliche Neubildung aller reifen Blutzellen - ein Leben lang. Diese Eigenschaft wird seit Jahrzehnten klinisch für Knochenmarktransplantationen genutzt, um unheilbare Erkrankungen des Blutsystems zu therapieren. Ob es Unterschiede in der Teilungsrate von Blutstammzellen gibt und damit Unterschiede in der Menge der produzierten reifen Zellen, war bisher nicht bekannt. Das Team um die Stammzellbiologin Dr. Claudia Waskow vom DFG-Forschungszentrum für Regenerative Therapien Dresden - Exzellenzcluster an der TU Dresden (CRTD) konnte nachweisen, dass es zwei Populationen von Stammzellen gibt, die sich in ihrer Teilungsrate unterscheiden. Zusätzlich zeigte sie, dass diese Funktion in jeder Stammzelle codiert
