Contain self antigen: Cells that make up the body's tissues are covered with surface markers, or antigens. The various RBC antigens found on the body's own cells are known as "self-antigens", and the immune system does not attack these. The membrane of each red blood cell contains millions of antigens. When receiving blood transfusions, the host immune systems will attack any donor RBC containing antigens different from their self-antigens.
