What Is Involved In Being A Bone Marrow Donor
Bone marrow donation, or bone marrow harvesting, is a procedure used by healthcare providers to obtain hematopoietic cells (stem cells) for bone marrow transplantation. To carry out the procedure, doctors use large, hollow needles to remove bone marrow from the donor’s thighs (pelvic bones). Donating bone marrow is painless and can cure someone with blood cancer or blood disorders.
Bone Marrow Donation
Donating bone marrow, or harvesting bone marrow, is a procedure used by healthcare providers to obtain blood-forming cells (stem cells) for a stem cell transplant (bone marrow transplant). The bone marrow donation process begins when someone agrees to donate bone marrow. Donating bone marrow is painless and can cure someone with blood cancer or blood disorders. To carry out the procedure, doctors use large, hollow needles to remove bone marrow from the donor’s thighs (pelvic bones). Anyone can donate bone marrow voluntarily, but all donors must meet certain health requirements.
Donating bone marrow is one of three ways health care providers obtain healthy stem cells. Most stem cell transplants involve peripheral blood or umbilical cord stem cell transplants. Peripheral stem cells are immature stem cells found in the bloodstream. Cord blood comes from the umbilical cord. Individuals who have recently given birth can choose to donate cord blood at a later date.
People in need can receive bone marrow donated by family members (related donors) or people they do not know (unrelated donors). According to the US Health Resources and Services Administration, 20% of related donor transplants and 14% of unrelated donor transplants completed in 2020 were bone marrow transplants.
Bone marrow is the soft, spongy liquid tissue found in the center of some bones. Every day, the bone marrow produces more than 200 billion new blood cells, including red blood cells, white blood cells, and platelets. A bone marrow transplant can help people with certain diseases, such as the blood disease aplastic anemia, or blood cancers such as non-Hodgkin’s lymphoma. In a bone marrow transplant, stem cells from healthy bone marrow replace the infected bone marrow.
Is Bone Marrow Transplant 100% Successful?
Each year, around 18,000 people learn they have a bone marrow disease that could be cured with a bone marrow transplant or other stem cell transplant.
The challenge is to find a partner. The best possible match is a healthy donor with human leukocyte antigens (HLA) that is highly compatible with the person needing a bone marrow transplant. HLA are blood proteins. Health care providers identify HLA by comparing blood test results on potential donors and recipients. This is HLA typing.
To find good matches between donors and recipients, providers screen donor stem cells for recipient-matched antigens. A large number of compatible antigens help the donated stem cells to produce new blood cells to replace the infected blood cells.
About 30% of all people who need a transplant find a compatible donor from someone in their immediate family. The remaining 70% depend on finding compatible donors from someone other than a close family member.

Yes, it is. There is a relationship between race and bone marrow compatibility. Certain genes control immunity. These genes may vary by race or ethnicity. Fewer people of color donate bone marrow, limiting the number of people who can receive donated bone marrow.
For example, the Be the Match© registry had more than 9 million bone marrow donors in 2021. A white person needing a bone marrow transplant had a 79% chance of finding a donor.
In comparison, a black person in need of a bone marrow transplant has a 29% chance of finding a donor. Health care and transplant organizations are working to increase the number of bone marrow and other stem cell donors from diverse racial and ethnic groups.
In the United States, the National Marrow Donor Program (NMDP) maintains a registry of potential donors. You can join the register:
Bone Marrow Registry
Many things can disqualify you from donating bone marrow. For example, people aged 60 and over cannot be donors. Transplant organizations set this age limit because many people develop medical conditions as they age that can disqualify them as donors. Medical conditions that rule out potential donors include:
This list represents just a few reasons why you may not be able to donate bone marrow. If you want to donate bone marrow but are not sure if you are eligible, talk to your healthcare provider. They can review medical guidelines and your health history.
Healthcare providers will do a final check of your overall health. They will give you information about how to prepare for general anaesthesia. You may have tests to confirm that you can donate bone marrow.
Health care providers filter the donated bone marrow to remove fat or bone particles. The donated bone marrow is processed in a laboratory so that it can be given to the recipient.

Most donors make a full recovery after donating bone marrow. It is important to remember that donating bone marrow is a surgical procedure that carries the following potential risks:
The biggest benefit is knowing that your bone marrow donation can save a life. The life you can save could be a family member, a friend, or someone you don’t know and may never meet.
Most donors can return to work or other normal activities after a few days of rest. It can take a few weeks for donors to fully recover from a bone marrow donation. The following side effects may occur during recovery:
Contact your healthcare provider if you have symptoms that could be signs of an infection. Symptoms may include fever and tenderness or redness in the area of the thigh where your healthcare provider inserted the needle to remove the bone marrow.
Donating Stem Cells
Yes, but these meetings only happen when the giver and receiver want to meet. Health care and transplant organizations that coordinate bone marrow donation also facilitate donor-recipient meetings.
Although millions of people in the United States register to donate bone marrow, more donors are always needed. For a bone marrow transplant to work, the match between donor and recipient must be as close as possible. The more people who sign up to donate, the more likely it is that someone battling blood cancer or a life-threatening blood disorder will receive a transplant. If you would like to learn more about donating bone marrow, talk to your healthcare provider. You can also contact the National Marrow Donor Program at 1.800.MARROW2. A large number of blood-producing stem cells live in the bone marrow. These cells become red blood cells, white blood cells, and platelets.
A stem cell transplant is a medical procedure to replace missing or damaged hematopoietic (hematopoietic or progenitor) stem cells with healthy stem cells. The procedure is also known as bone marrow transplantation (BMT) or hematopoietic cell transplantation (HCT).
The main source of stem cells is the bone marrow. Bone marrow is the soft, spongy material found in most bones in the body. The bone marrow acts as a blood cell factory, constantly producing new hematopoietic stem cells. These cells then mature into cells that become:
Stem Cell (bone Marrow Transplant)
Stem cell transplants can be used to treat some childhood cancers, sickle cell anemia, and some other blood or immune system disorders. The transplant process is complicated. It is an important medical procedure and can cause serious side effects. Your care team will let you know if your child could have a stem cell transplant.
Not all patients are candidates for transplant. The medical team will consider factors such as:
Laboratory tests will measure blood count, kidney function, liver function, and exposure to infectious diseases. Your child will also have tests to check the heart, lungs, kidneys and other vital organs.
You will also meet with members of the care team, such as a social worker or psychologist, to talk about emotional and mental health. A financial advisor can help with insurance approval and financial questions.
Role Of Donors In Bone Marrow Transplants
Transplant patients usually stay in hospital for 4 to 6 weeks or more. Your child is staying in a special part of the hospital for transplant patients and other patients with weak or no immune system function. Infection control guidelines in the transplant unit are different to other parts of the hospital.
The transplant process is complicated. But getting stem cells is relatively easy. It is very similar to a blood transfusion. The stem cells are in a bag or syringe which is connected to your child’s central line through a tube. It takes from a few minutes to a few hours. It is not painful.
After entering the bloodstream, the stem cells travel to the bone marrow. This is where they start to divide. Stem cells become white blood cells, red blood cells and platelets. This process is called grafting. Grafting usually begins 2 to 4 weeks later
