  Bone Marrow Transplant Information
The bone marrow is extracted from the patient prior to transplant and may be "purged" to remove lingering malignant cells (if the disease has afflicted the bone marrow).
A good bone marrow transplant program will also recognize the importance of providing patients and their families with emotional and psychological support before, during and after the transplant, and will make personal and other support systems readily available to families for this purpose.
As the patient waits for the transplanted bone marrow to migrate to the cavities of the large bones, set up housekeeping or "engraft," and begin producing normal blood cells, he or she will be very susceptible to infection and excessive bleeding.

  Bone marrow - Wikipedia, the free encyclopedia
Bone marrow (or "medulla ossea") is the tissue comprising the center of large bones.
While the majority of long bones are formed of cortical ("compact") material; at the ends are the epiphysis, which are generally composed of cancellous ("spongy") material and red marrow.
Bone marrow is a source of protein and high in monounsaturated fats.

 Bone marrow transplant - Wikipedia, the free encyclopedia
Bone marrow transplantation (BMT) or hematopoietic stem cell transplantation (HSCT) is a medical procedure in the field of hematology and oncology that involves transplantation of hematopoietic stem cells (HSC).
In the case of a bone marrow transplant, the HSC are removed from a large bone of the donor, typically the pelvis, through a large needle that reaches the center of the bone.
After several weeks of growth in the bone marrow, expansion of HSC and their progeny is sufficient to normalize the blood cell counts and alleviate the need for red blood cell and platelet transfusions.

 Bone Marrow
Bone marrow is a spongy tissue found in the breast bone (sternum), ribs, hip bones (pelvis), skull, and spine.

 Bone marrow donors
Bone marrow tissue, found in the hollow centre of our long bones, is the factory where new blood cells are made.
Without marrow our bodies would be unable to produce the white cells we need to fight infection, the red blood cells we need to carry oxygen and the platelets we need to stop bleeding.
As with blood donors, bone marrow donors will be required to answer specific questions relating to the risk of transmitting infections to the person who receives the donation.

 Bone Marrow Aspiration and Biopsy
A bone marrow biopsy removes a small amount of bone and a small amount of fluid and cells from inside the bone (bone marrow).
A bone marrow aspiration can also be done to collect bone marrow for medical procedures, such as stem cell transplantation or chromosomal analysis.
For a stem cell transplant, bone marrow aspiration will be done at several places on the body (generally from the back of the pelvic bone) to remove enough bone marrow cells for the transplant to work.
