Stem cell transplant, also known as bone marrow transplant, is a medical procedure used to replace damaged or destroyed bone marrow with healthy stem cells. These stem cells can develop into red blood cells, white blood cells, and platelets—crucial components of the blood. It is commonly used to treat certain types of cancers and blood-related disorders. The procedure involves collecting healthy stem cells from the patient or a donor and introducing them into the patient’s body after high-dose chemotherapy or radiation therapy. These stem cells then migrate to the bone marrow, where they regenerate new, healthy blood cells. The transplant helps: There are three primary types of stem cell transplants, based on the source of the stem cells: In this type, stem cells are collected from the patient before treatment and then reintroduced after chemotherapy or radiation. It is commonly used in lymphoma and multiple myeloma. Stem cells are collected from a donor—often a sibling or matched unrelated donor. This type is used for leukemia, blood cancers, and certain genetic disorders. Stem cells are collected from the umbilical cord and placenta after birth and stored for later use. These are rich in immature stem cells and are less likely to cause immune rejection. The process involves several stages: Stem cell transplants provide several important benefits: As with any major procedure, stem cell transplants come with possible risks and side effects: Advances in stem cell research and transplantation techniques are improving success rates, minimizing side effects, and expanding the availability of donor matches.
