The Nature of Blood Stem Cells and Bone Marrow
Q: What are blood stem cells and why are they so vital?
A: Blood Stem Cells are the basic building blocks of our blood. They produce vital blood components, such as white cells which fight infection, red cells which carry oxygen, and platelets which prevent bruising and bleeding. Any disease that attacks your bone marrow, where your blood stem cells are most often located, may eliminate your body’s ability to protect itself. Most fatal blood diseases have traditionally been fought with radiation or chemotherapy. In countering disease, both forms of treatment may seriously damage the human body. By providing patients in need of compatible blood stem cells, you can give them a second chance at a healthy life.
Q: Where do you get blood stem cells?
A: Blood Stem Cells used in transplants can be found in your bone marrow, and to a much lesser extent in your circulating blood. They are also found in a baby’s umbilical cord blood.
Q: What is bone marrow?”
Blood Stem Cell Transplantation
Q: Who needs a bone marrow transplant?
A: Bone marrow transplantation is a proven cure for patients with aplastic anemia, some leukemias, lymphomas, and diseases of the immune system.
Q: Must donor and patient be related?
A: Initially, bone marrow donors were sought only among family members. However, approximately 70% of patients needing a transplant do not have a family member who is a compatible donor. Through HLA typing, non-related compatible donors can be identified and used successfully in a bone marrow transplant
Q: How is a donor matched to a patient?
A: When you register to become a donor, you provide a cheek swab sample. From that sample, we are able to obtain what is called your ’tissue type’ or your ‘HLA type’. This string of markers is what we use to match a patient to a donor.
Q: What is HLA?
A: HLA stands for Human Leukocyte Antigens, they are ‘markers’ on the white blood cells. These antigens are inherited characteristics, just as is the color of one’s eyes and hair or skin. In a tissue transplant, the closer the match in HLA type between the donor and the recipient, the greater the chance that the transplant will be successful. Due to these genetic factors, patients have the best chance of finding a donor who is the same racial or ethnic background.
Q: What are the odds of matching HLA types?
A: A patient’s likelihood of having a donor on the Be The Match Registry who is willing and able to help save a life is estimated to range from 66% to 93%, depending on race and ethnicity. Cord blood improves likelihood of finding an appropriate cell source. In 2012, 39 percent of diverse patients who received a transplant used cord blood.

Q: How do patients receive donated blood stem cells?
A: Patients receive donated blood stem cells much like a regular blood transfusion. The difference between the two is that before receiving the stem cells, a patient needs to undergo very intensive chemotherapy to wipe out his/her remaining bone marrow and immune system. Once the immune system is completely destroyed, the donor’s blood stem cells are administered like a blood transfusion. Then, if all goes well, the stem cells will make its way to the patient’s bone marrow and will start producing new stem cells.
Becoming a Potential Bone Marrow/Blood Stem Cell Donor
Q: Who is Asian American Donor Program and how are they related to the Be The Match?
A: AADP began its NMDP affiliation in 1989. AADP is a community based non-profit, for social benefit (501©3) organization specialized in conducting outreach and donor registration drives in and with diverse communities. AADP is an official recruitment center of the Be The Match Register. AADP was started in 1989.
Q: How do you become a bone marrow donor?
A: Please visit our How to Become a Donor page. The first step to being a donor is to register as a member on the Be The Match Registry, by complete a donor consent form. Second, a cheek swab sample is taken to determine your Human Leukocyte Antigen (HLA) type. The HLA type is, on be The Match Registry. If you are identified as a potential match, you are contacted for additional blood tests. If tests reflect a potentially successful match, a detailed information session is arranged so that you can decide whether or not to proceed. If you decide to proceed, you are provided a full health screening before the actual bone marrow or PBSC collection.
Q: Why are younger donors preferred?
A: If you are between the ages of 18 and 44, patients especially need you. If more than one potential donor is a good HLA match for a patient, doctors will also consider other factors, including the donor’s age. Research shows that cells from younger donors lead to more successful transplants. That’s because younger donors produce more and higher-quality cells than older donors.
Q: How do I register for the Be The Match registry?
A: You can register by attending one of AADP’s drives. Visit our calendar for a listing of all our upcoming drives. When you come to register, please remember to bring complete information of two contacts who do not live with you and who do not live with each other. If none of our drives are convenient for you, Click here and request that a home kit be mailed to you.
Q: What information do you need from me when I register?
A: We will need the following information from you in order to register
- Complete a donor registration form which includes:
- A short health history questionnaire
- Personal identifying information
- Provide the name and address of two contacts that do not live with you or with each other.
- We need to collect a tissue sample from the inside of your cheek using a swab kit.
Q: How much time does it take to become a donor?
A: Registering, completing the consent form and swabbing the inside of your cheek will take approximately 15 minutes. Identifying your HLA tissue type and listing you on the Registry could take 8 to 10 weeks. If you are identified as a potential donor for a specific patient and you are selected to donate bone marrow or PBSC, it could take up to 30 hours of your time over a 3 to 4 month time period.
When You Are Called As A Match
Q: What is the Bone Marrow Donation Process?
A: The bone marrow is collected from the donor during a surgical procedure using a special needle inserted into the hip bone and NOT the spine. The procedure is usually performed in the hospital operating room, as an outpatient service, but may require a donor to spend one night in the hospital. For a more detailed explanation, please visit our Donation Process page.
Q: What is the PBSC Donation Process?”
A: For four or five days before the PBSC donation, the donor is given an injection of a medication called Filgrastim to increase the number of stem cells released into the blood stream. After receiving the medication, peripheral blood stem cells can be collected through the process of apheresis. Donating PBSC is similar to donating platelets at a blood bank. The donor’s blood is removed through a sterile needle placed in a vein in one arm and passed through an apheresis machine that separates out the stem cells. The remaining blood, minus the stem cells, is returned to the donor through a sterile needle in the other arm.
- Keep us updated if your contact information changes, you have significant health changes or you change your mind about being a donor
- Respond quickly if you are contacted as a potential match for a patient
- Donate to any searching patient who matches you
- Be listed on the registry until your 61st birthday, unless you ask to be removed
You have the right to change your mind about being a donor at any time. Donating is always voluntary. If you decide you do not want to donate, let us know right away. That way we can continue the search for another donor without dangerous delays for the patient.
