Voluntary donation of bone marrow, why do donors have the right to go back on their word?

Have the right to go back on our word

1, bone marrow donors collected hematopoietic stem cells, but originally extracted bone marrow blood. Because bone marrow blood is rich in hematopoietic stem cells, it was originally called donating bone marrow. Hematopoietic stem cells are directly collected from peripheral blood, and the process is the same as donating blood component.

2. Donating hematopoietic stem cells will not have adverse effects on the health of donors. Many kinds of blood cells in the body come from the same ancestor-pluripotent hematopoietic stem cells, which can not only differentiate into children and grandchildren, but also replicate the same cells as themselves, thus making our hematopoietic function endless.

3. Donation procedures include physical examination and laboratory examination; Those who pass the medical examination fill in the relevant forms and sign the donation volunteers; The staff took 5 ml of venous blood for HLA typing, and entered the examination data into the bone marrow database.

4. When a patient needs a bone marrow transplant, look for a matching donor in the bone marrow bank. If your information is the same as the patient's, then you can realize your wish to donate bone marrow.

Donation procedure

General: ① Physical and laboratory examination; Those who pass the medical examination fill in the relevant forms and sign the donation volunteers; ③ The staff took 5 ml of venous blood for HLA typing, and the examination data were entered into the hematopoietic stem cell database; ④ When patients need hematopoietic stem cell transplantation, look for a matching donor in the hematopoietic stem cell bank. If your information is the same as the patient's, then you can realize your wish to donate hematopoietic stem cells.

Impact of donation

Donating hematopoietic stem cells will not have adverse effects on the health of donors. Many kinds of blood cells in our body all come from the same ancestor-pluripotent hematopoietic stem cells. He can not only differentiate his children and grandchildren, but also reproduce cells exactly like himself. In this way, our hematopoietic function is endless. When old blood cells die, new blood cells grow to replace them; When some hematopoietic stem cells are damaged, healthy stem cells will be born soon to make up for it. Our bodies are really in harmony.

Pluripotent stem cells are few in number and distributed throughout the bone marrow. When donating bone marrow, only a small part of human bone marrow is extracted, and only a part of pluripotent stem cells are lost. The remaining pluripotent stem cells will replicate rapidly, and the hematopoietic function will completely return to normal in a short time. Therefore, donating hematopoietic stem cells will not affect people's hematopoietic function.
