Yes, it is not common, but host-graft rejection sometimes leads to an overwhelming immunologic reaction - against your own body - and this can be fatal, if untreated.
In a bone marrow transplant, the patient receives healthy stem cells to replace their damaged or diseased bone marrow. The harvesting process involves collecting these healthy stem cells from either the patient (autologous transplant) or a donor (allogeneic transplant). The harvested cells are then given back to the patient after undergoing certain treatments to help rebuild their immune system and blood cells.
Yes, an O negative patient can receive a bone marrow transplant from an O positive donor, but it is not ideal. The recipient's body may see the O positive blood cells as foreign and attack them, which can lead to complications such as graft-versus-host disease. It is generally recommended to match blood types as closely as possible for bone marrow transplants.
The procedure in which donor marrow or stem cells are injected into a patient is called a stem cell transplant or bone marrow transplant. It typically involves first collecting stem cells from a donor, either from their bone marrow or peripheral blood. The patient then undergoes conditioning treatment, which may include chemotherapy or radiation to prepare their body to accept the new cells. Finally, the harvested stem cells are infused into the patient's bloodstream, where they can migrate to the bone marrow and start producing new blood cells.
The marrow in the medullary cavity is primarily composed of yellow marrow, which stores fat, while the marrow in the spongy bone is red marrow where blood cells are produced. Yellow marrow is found in long bones, whereas spongy bones contain red marrow in their trabeculae.
An autologous stem cell transplant is usually needed when a disease has damaged or destroyed bone marrow. Some diseases include Hodgkin's lymphoma, leukemia, multiple myeloma, and asplatic anemia.
Autologous bone marrow transplant
An autologous bone marrow transplant uses the patient's own bone marrow. The bone marrow is collected from the patient, stored, and later reinfused after high-dose chemotherapy or radiation therapy. This type of transplant helps restore the patient's immune system.
Autologous = own marrow Allogeneic = transplant from a related (or tissue matched) donor. Syngeneic = transplant from an identical twin.
allogenic
The term for bone marrow from a close relative is "allogeneic bone marrow transplant."
yes, because if doctors mess up and accidentally breaks you bone marrow, you will not produce any more blood in your body.
In a bone marrow transplant, the bone marrow used typically comes from a donor who matches the recipient's tissue type. This matching helps reduce the risk of rejection. The bone marrow is usually harvested from the donor's hip bones using a needle.
You have to get a bone marrow transplant.

The first successful bone marrow transplant was in 1973.
A bone marrow transplant can change a person's blood type to that of the donor's. This is because the bone marrow produces blood cells, including red blood cells that determine blood type. After a transplant, the new bone marrow starts producing blood cells with the donor's blood type.
Either a bone marrow or a stem cell transplant (although these days most stem cell transplants are obtained from blood).
