![]() Indeed, Rh stands for rhesus, because it was identified on the red blood cells of rhesus monkeys before it was found on human red blood cells.Īll of this means that a human can be ABO and Rh matched for blood products from a monkey, or even better, a great ape such as a gorilla or chimpanzee (who are closer to us on the evolutionary tree than monkeys). They also apply to our close relatives in the animal kingdom, especially other primates. It turns out, however, that the ABO and Rh blood groups are not limited just to human populations. The main ones are the ABO and Rh antigens (the positive or negative seen after the more commonly known A, B, O types) and for people to receive blood products they must be appropriately ABO and Rh matched. That’s because our immune system senses molecules on the surface of red blood cells and reacts aggressively to certain surface molecules, or markers, in an individual whose on red blood cells don’t have the same kind.īut while there are literally hundreds of different surface markers that make red blood cells different between people, only a handful of markers act as strong antigens to the immune system. Instead, humans are divided into blood groups that determine who can receive blood from whom without suffering a severe immune reaction that can be fatal. ![]() This may surprise many people as most are aware that even humans are not universally transfusion-compatible. Would you accept a transfusion of blood products from a chimpanzee or a gorilla? Or what about a pig? One person did back in 1667 when French physician Jean-Baptiste Denis successfully transfused blood from a lamb into 15 year-old human boy. Is the Genetic Literacy Project a corporate ‘front’?
