Blutverlust, Infektionen, Entzündungen: Es sind alltägliche Gesundheitsprobleme, die die Blutstammzellen im Knochenmark immer wieder aus ihrem Schlafzustand reißen und zur Teilung anregen. Dabei sammeln sich regelmäßig Erbgutdefekte an, die schließlich zum Versagen der Stammzellen führen können, wie Wissenschaftler vom Deutschen Krebsforschungszentrum und vom Stammzellinstitut HI-STEM nun in der Zeitschrift Nature veröffentlichen. Die Forscher zeigten an normalen Mäusen, wie es zu dieser typischen Alterserscheinung kommt. Bei Mäusen mit einem defekten Erbgut-Reparatursystem führte die wiederholte Aktivierung der Blutstammzellen sogar zum völligen Versagen des Knochenmarks und damit zu Symptomen des vorzeitigen Alterns. Die Erbgutschädigungen stehen auch im Verdacht, Stammzellen zu Krebs entarten zu slyijb.
