Bone marrow is the soft, spongy fatty tissue inside the bones. The bone marrow is the medium for development and storage of most of the body’s blood cells. Stem cells are immature cells in the bone marrow that give rise to all of the different blood cells. It is the stem cells that are needed in bone marrow transplant.
What is bone marrow transplant (BMT)?
A bone marrow transplant is a procedure performed to replace damaged or destroyed bone marrow stem cells with healthy bone marrow stem cells. The procedure involves extracting the healthy stem cells, filtering those cells, and giving them back, either to the donor himself, or to another person (the recipient). The goal of BMT is to transfuse healthy stem cells into a person, after his or her own unhealthy bone marrow has been treated to kill the abnormal cells.
