Bone marrow stem cells, the source of immune cells, lose their mojo over time. Can research help them go an extra mile?
Ah, the aging process. Over time, cells lose the spring in their step, and tissues and organs aren't maintained the way we like them to be. The same holds true for our bone marrow stem cells. Long-lived cells of this type decline in their ability to generate the cell types that derive from them, including immune cells, which raises the risk of infections for elderly patients.
