Bone marrow collected from a close relative is referred to as?

The term used to describe bone marrow collected from a close relative is "allogenic." In a medical context, allogenic refers to tissue or cells that are transplanted from a donor to a recipient who is genetically different but often closely related. This type of transplant is commonly used in cases of bone marrow transplants, where a relative might serve as the donor to ensure compatibility in terms of human leukocyte antigens (HLAs), which are crucial for reducing the risk of rejection.

Autologous refers to tissues or cells harvested from the same individual receiving the transplant. Xenogeneic pertains to tissues from different species, and syngeneic identifies tissues or cells that come from genetically identical sources, such as identical twins. In this scenario, the focus on close familial relationships makes allogenic the correct choice for describing the source of the bone marrow.
