Bone marrow transplantation
Bone Marrow Transplantation
Bone marrow transplantation (pronunciation: /boʊn ˈmær.oʊ ˌtræns.plænˈteɪ.ʃən/) is a medical procedure that involves the transplantation of hematopoietic stem cells, which are typically found in the bone marrow. This procedure is often performed on patients suffering from diseases such as leukemia, lymphoma, and multiple myeloma.
Etymology
The term "bone marrow transplantation" is derived from the English words "bone", "marrow", and "transplantation". "Bone" and "marrow" refer to the spongy tissue inside bones where blood cells are produced, while "transplantation" refers to the act of transferring something from one place to another.
Procedure
The procedure begins with the extraction of bone marrow from a healthy donor. The marrow is then processed and transplanted into the patient's body, where it begins to produce new, healthy blood cells. This process is known as engraftment.
Types of Bone Marrow Transplantation
There are two main types of bone marrow transplantation: autologous transplantation and allogeneic transplantation. In autologous transplantation, the patient's own bone marrow is used, while in allogeneic transplantation, the bone marrow comes from a donor.
Risks and Complications
Like all medical procedures, bone marrow transplantation carries certain risks and potential complications. These may include graft-versus-host disease (GVHD), infection, and organ damage.
