Bone-marrow transplants are performed for many [[leukemias]] and [[lymphomas]], among other diseases. If a person receives bone marrow from someone who is a different ABO type (e.g., a type A patient receives a type O bone marrow), the patient's blood type will eventually convert to the donor's type.
