What is bone marrow collected from a close relative called?

Bone marrow collected from a close relative is called "related donor bone marrow" or "autologous bone marrow" if the donor is the same patient. When the marrow is collected from a sibling or another family member, it is often referred to as "allogeneic bone marrow" from a related donor. This type of donation can be crucial for treatments like bone marrow transplants, particularly in cases of certain blood disorders or cancers.
