bone marrow aspiration

Removal of bone marrow fluid via a needle to diagnose a number of conditions, including leukemia, lymphoma, and multiple myeloma. Bone marrow aspiration is also used for bone marrow transplantation. See bone marrow transplantation.

bone marrow

the soft, organic material in the cavities of bones, a network of blood vessels and special connective tissue fibers that hold together a composite of fat and blood-producing cells.
The chief function of bone marrow is to manufacture erythrocytes, leukocytes and platelets. These blood cells normally do not enter the bloodstream until they are fully developed, so that the bone marrow contains cells in all stages of development. If the body's demand for white cells is increased because of infection, the bone marrow responds immediately by increasing production. The same is true if more red blood cells are needed, as in hemorrhage or anemia.
There are two types of bone marrow, red and yellow. The former produces the blood cells; the latter, which is mainly formed of fatty tissue, normally has no blood cell-producing function.

bone marrow aplasia

bone marrow displacement
bone marrow dyscrasia
abnormal cell production by the bone marrow. Occurs in some dog breeds, especially Poodles, in which there are maturation abnormalities of erythrocytes with macrocytosis and hypersegmented neutrophils.
bone marrow spaces
the cavities in cancellous bone that are usually filled with bone marrow.
bone marrow suppression
some drugs and infectious agents can cause reduced erythropoiesis, myelopoiesis and megakaryocytopoiesis. See also anemia, pancytopenia.

bone marrow transplantation
the transfer of bone marrow from a normal, antigenically matched individual to another, usually for treatment of aplastic anemia, immunodeficiency or metabolic disorders.
