The optimal donor is a histocompatible (HLA) matched relative who is usually a sibling or, in rare cases, a parent or grandparent with identical HLA tissue typing. Everyone inherits two sets of chromosomes containing HLA genes, four genes per set.
Can a sibling donate bone marrow?

What happens if you give O Negative blood?
Transfusion Reactions. In most cases, O-negative blood can be safely given to anyone because it does not contain any of the major antigens that can trigger a severe immune response, known as a transfusion reaction. In a transfusion reaction, antibodies in the recipient’s bloodstream attack antigens on the donor’s red blood cells.
Is only O-Negative blood compatible with other blood types?
Only O-negative blood is considered compatible with all other blood types, and even this is not always true. Your blood is one of four types — A, B, AB or O. This is called the ABO blood typing system. Blood typing is based on the presence or absence of blood cell antigens A and B.
Why are there medical guidelines for bone marrow donation?
Medical guidelines when you match a patient. Bone marrow donation guidelines protect the health of donors and the patients receiving donated cells. These guidelines ensure that it is safe for you to donate and that your donation will provide the best possible outcome for the patient.
Can I donate stem cells or bone marrow to a relative?
