Web1 de mai. de 2011 · Triple knockout mice of FoxO1, FoxO3, and FoxO4 exhibited defective long-term repopulating activity of HSCs, which correlated with increased cycling and apoptosis of HSCs, as well as increased levels of ROS in HSCs [106]. Similarly, the HSC compartment in FoxO3a null mice suffers from augmented levels of ROS and … WebPreviously, we showed that phenotypic HSCs (pHSCs) are variable in their reconstitution potential and that Hoxb5 expression distinguishes long-term from short-term repopulating HSCs . While Hoxb5 − pHSCs were unable to repopulate secondary recipients and were homogeneously lymphoid-biased, Hoxb5 + pHSCs serially reconstituted recipients and …
