Bone Marrow Transplantation


By rickie wright at 2010-12-02 00:33:20
Bone marrow is an important part of human life. It is a flexible tissue that is found in the hollow interior of bones. Bone marrow exists in two forms. There are red and yellow. Almost 100 percent of bone marrow at birth falls into the red bone marrow category. Red consists of myeloid tissue, red blood cells, platelets and white blood cells. Yellow consists of fat cells and some white blood cells can develop in yellow bone marrow. Both the red and yellow contain various capillaries and blood vessels.

The red converts itself to yellow over time. The red can be found in flat bones. Flat bones are found in the hip, the breast, the skull, the ribs, the shoulder blades and vertebrae. Yellow bone marrow is found in the hollow interior of the middle portion of bones. If there is ever a severe condition of blood loss; the body has the ability to convert the yellow back to red bone marrow to increase blood cell production.

Bone Marrow is the "blood cell factory" which is found filling up the cavities of bones. All blood cells originate and are produced from a single "stem cell" whose progeny grow and mature into different types of blood cells. This stem cell can and does renew itself as required by our body.

Stem cells are made in the bone marrow and mature into red blood cells, white blood cells and platelets. When they go rogue and produce defective or cancerous cells, one way to stop them is to "reboot" the bone marrow with a transplant of healthy cells.

Bone marrow transplant is a treatment that saves the lives of people suffering from deadly diseases such as cancer, but like all transplants, it is suffering from lack of donors.

The role of the marrow is to produce all the formed elements of the blood: red blood cells (or erythrocytes), white blood cells (or leucocytes) and platelets (or thrombocytes).

Normally, these cells are continuously renewed through a stock of stem cells in the bone marrow, i.e., "virgin" cells which can evolve in all types of cell.

This marrow is located in the center of long bones like the humerus in the arm, and flat bones, such as pelvic bone in the pelvis. It is very different from the spinal cord, which is part of the nervous system located in the channel formed by the stacking of the vertebrae.

A marrow transplant involves taking a sample of bone marrow from a donor and reimplanting it in a patient.

Several diseases can be treated by this act. This is the case of leukemia and lymphoma, because in these diseases, cancer cells invade the marrow and then prevent it from functioning properly.

This is also the case of aplasia in which bone marrow is no longer functioning and no longer produces white blood and red blood cells.

Finally, we can also make a transplant when a harmful treatment destroys the bone marrow and therefore its cells: when there is no more red blood cells, there is a risk of anemia. The lack of white blood cells leads to infections, and disappearance of platelets is a source of bleeding.

Two Types of Transplants:

The allograft, which uses donors, and the donor can be unrelated or part of the family (family related donor). Of course, the chances of finding a stranger with a compatible marrow, therefore accepted by the patient, are much rarer than in the case of a brother or sister.

Transplants are much more effective when the donor is related to the recipient. The problem is that in a family, only one child in four has the same HLA system as his sick brother.

Finally, there is the autologous bone marrow transplant, which uses the patient's own marrow. It is collected, frozen during an aggressive treatment of the patient and then reimplanted later.
