Bone marrow is a spongy substance found in the center of the bones. It manufactures bone marrow stem cells and other substances, which in turn produce blood cells. Each type of blood cell made by the bone marrow has an important job. Red blood cells carry oxygen to tissues in the body.

The bottom line There are two types of bone marrow. Red bone marrow is involved in production of blood cells, while yellow marrow is important for fat storage.

A bone marrow transplant takes a donor's healthy blood-forming cells and puts them into the patient's bloodstream, where they begin to grow and make healthy red blood cells, white blood cells and platelets. Patients receive high doses of chemotherapy to prepare their body for the transplant.

With bone marrow disease, there are problems with the stem cells or how they develop: In leukemia, a cancer of the blood, the bone marrow makes abnormal white blood cells. In aplastic anemia, the bone marrow doesn't make red blood cells. In myeloproliferative disorders, the bone marrow makes too many white blood cells.

Functions of blood Blood has three main functions: transport, protection and regulation. Blood transports the following substances: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body. Nutrients from the digestive tract and storage sites to the rest of the body.

These include blood and bone marrow cells. Hematological tests can help diagnose anemia, infection, hemophilia, blood-clotting disorders, and leukemia.

In bone marrow biopsy, your doctor uses a needle to withdraw a sample of the solid portion. In bone marrow aspiration, a needle is used to withdraw a sample of the fluid portion. Bone marrow biopsy and bone marrow aspiration are often done at the same time. Together, these procedures may be called a bone marrow exam.

Erythropoietin stimulates the bone marrow to produce more red blood cells. The resulting rise in red cells increases the oxygen-carrying capacity of the blood. As the prime regulator of red cell production, erythropoietin's major functions are to: Promote the development of red blood cells.

Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2]. Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4].

Bone marrow also contains multipotent stem cells that give rise to all blood cell types but not other cells. ... This particular stem cell has been found to give rise to bone, muscle, cartilage, fat, and other similar tissues. Multipotent stem cells are essentially committed to produce specific cell types.
