Observing stem cells maturing into blood cells in living mouse

When Busch turned on the marker in adult animals, it became visible that at least one third (approximately 5000 cells) of a mouse's hematopoietic stem cells produce differentiated progenitor cells. "This was the first surprise," says Busch. "Until now, scientists had believed that in the normal state, very few stem cells -- only about ten -- are actively involved in blood formation."

"When we transplanted our labeled blood stem cells from the bone marrow into other mice, only a few stem cells were active in the recipients, and many stem cells were lost," Rodewald explains. "Our new data therefore show that the findings obtained up until now using transplanted stem cells can surely not be reflective of normal hematopoiesis. On the contrary, transplantation is an exception [to the rule]. This shows how important it is that we actually follow hematopoiesis under normal conditions in a living organism."
