National Marrow Awareness Month – November 2025

National Marrow Awareness Month is observed in November to acknowledge the achievements of transplant physicians. This month also honors the people who donate their stem cells and bone marrow which helps in giving patients a second chance at life. This month generates awareness about the importance of bone marrow transplants and encourages people to donate. Found inside the bones, marrow is a spongy material that contains stem cells. These cells eventually become white blood cells, red blood cells, and platelets. They have different important functions to keep the body healthy and strong. Patients with life-threatening diseases need these healthy stem cells to live a longer life.

History of National Marrow Awareness Month

The first human bone marrow transfusion is said to have been given to a patient with aplastic anemia in 1939. The patient required daily blood transfusions, and doctors attempted to raise her leukocyte and platelet count using intravenous injection of bone marrow. In 1956, Barnes and his colleagues published their experiment on two groups of mice with acute leukemia. They noted the ability of the new engrafted immune system to prevent leukemia relapse and the activity of the engrafted immune system against the recipient.

In 1960, the first successful bone marrow transplant took place, which used bone marrow from an identical twin. In 1968, the first successful bone marrow transplant using marrow from a sibling who was not an identical twin occurred. The first registry in the world to recruit unrelated bone marrow donors was created by the Anthony Nolan charity in London, England. In the U.S., the registry to recruit bone marrow donors was established in 1979, which was originally called the National Marrow Donor Registry; it is now renamed ‘Be The Match.’

In the early 1980s, research on autologous transplants, transplants that use patients’ own stem cells instead of donor cells, began, and now autologous transplants are performed more than transplants using donor cells. In 1990, B.T.M. InfoNet was created, which provides patients with information and support before, during, and after the transplant, and it is a big help to the patients.
