Aged bone marrow niche restrains function of rejuvenated HSC

Aged bone marrow niche restrains function of rejuvenated HSCs, shows study
When leukemia strikes an older person, it is in part due to the aging of his or her hematopoietic stem cells (HSCs). These immature cells can develop into all types of blood cells, including white blood cells, red blood cells and platelets. As such, researchers have focused on rejuvenating HSCs as a way to treat leukemia.
A new study released today in
STEM CELLS adds much to that level of knowledge by showing that the youthful function of rejuvenated HSCs upon transplantation depends in part on a young bone marrow "niche," which is the microenvironment surrounding stem cells that interacts with them to regulate their fate.
