Outline of Final Research Achievements

We have established c-Myb reporter mice that can moniter the endogeous c-Myb protein. Utilizing the mice, we proved that c-Myb protein was able to control cell functions, especially HSCs, according to c-Myb expression levels. We have also confirmed the concepts of lineage-biased and dormant HSCs . We anticipate that these mice will become a new reserch tool that can efficiently isolate HSCs self-renewing from the embyonic to the adult stage.
