How do red bone marrow and yellow bone marrow differ in function?
Red bone marrow is involved in the production of blood cells, while yellow marrow is important for fat storage. As you age, yellow bone marrow replaces red bone marrow. The stem cells found in healthy bone marrow can be lifesaving for people living with certain autoimmune diseases and cancers.
Is heterogeneous bone marrow normal?
