From Internet:
The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells.
it should be blood and fat
are you sure?
Bone marrow is a soft, spongy tissue found inside our bones. It contains stem cells that can develop into different types of blood cells like red blood cells, white blood cells, and platelets. When a person has a diseased or damaged bone marrow, they might need a bone marrow transplant to replace the unhealthy cells with healthy ones.
There are two main reasons why people donate bone marrow:
1. Helping someone in need: People with diseases like leukemia, lymphoma, or certain immune disorders might require a bone marrow transplant to survive. If a patient doesn't have a compatible donor within their immediate family, they rely on finding a matching donor from the general population.
2. Bone marrow compatibility: To perform a transplant, the donor and the recipient need to have a close tissue match. Human leukocyte antigens (HLAs) are proteins on the surface of our cells that determine compatibility. Generally, the best chance of finding a match is within the same ethnic or racial group. The more people who join the bone marrow registry, the higher the chances are of finding a match for those in need.
To become a bone marrow donor, here's how you can do it:
1. Register with a donor program: Look for a reputable bone marrow registry or organization, such as Be The Match in the United States. You will need to provide some personal information and may be asked to fill out a health questionnaire.
2. Tissue typing: If your registration is accepted, you will be asked to provide a cheek swab or a blood sample for tissue typing. This process helps identify your HLA markers, which determine your compatibility with potential recipients.
3. Being a match: If you are identified as a potential match for someone in need, you may be contacted for further testing and evaluation. This may involve additional blood tests and a physical examination.
4. Donation process: There are two main methods for donating bone marrow: peripheral blood stem cell (PBSC) donation and marrow donation. PBSC involves a non-surgical procedure where blood is drawn from one arm, passed through a machine to collect the stem cells, and returned to the other arm. Marrow donation is a surgical procedure done under general anesthesia, where a needle is used to withdraw liquid marrow from the back of the pelvic bone.
It's important to note that donation is voluntary and the decision to donate is a personal one. Being a bone marrow donor can save someone's life and provides hope to those in need of a transplant.
