Blood types were once thought to be with multitude for lifetime . And , in almost every slip , they ’re still thought to be with a person for life . But there is one affected role whose rakehell character really changed . A liver transplantation , plainly , has a gibe of change a person ’s profligate eccentric .
There was once a simple time in human chronicle when everyone had just one rip type , and that blood type was O negative . It was n’t call O at the time , of class , because even if anyone was looking at it , it would just have been blood to them . But life kept up its common trick of evolving , and of a sudden , on the Earth’s surface of the lovely , bland , red rake prison cell were footling agglutination of protein . There was what ’s now known as the Rh element , the thing that turns O negative parentage into O positive blood . Then there were other little clumps of protein , which separated Rh positive blood and Rh negative stemma into A and B types . For the vast absolute majority of history , only the Rh element caused any trouble . The system of an Rh damaging woman who became pregnant with an Rh irrefutable child could see the baby ’s blood character as an outside body , and assail it . This was such a selector that today eighty - five percent of the great unwashed are Rh positive .
Meanwhile , A and vitamin B types only began distressful humankind by the time blood transfusions and organ transplants were happen . ( Before that , any human blood or organs enter the physical structure generally come via the stomach , which is n’t that fussy about roue type . ) Again , the resistant organisation would attack the queerly bedecked blood cells and do aesculapian problems . case O patient , roughly forty - five percent of the population , could give out their blood and organ , but could n’t receive anyone else ’s . The Rh factor of the origin depended on what type of medical routine was being done .

And so the world became concerned with these little blobs on lineage , and with the genes that caused them . Since it was genetical , blood eccentric was for life , and there was no way around the variations ( Two more of which were determine just recently . The Junior and Langereis , which bear upon about 50,000 people in Japan . ) so there was n’t anything to be done except finding ecumenical O negative giver and draining them like Capri Sun succus bags . So imagine people ’s surprise when they found out that rakehell case can change .
Technically , it depend on what people mean by roue type . The genes do n’t exchange . However , people notice that after bone marrow transplants , recovered patients sometimes slowly developed their bestower ’s rip types . The marrow was used making one kind of blood , and it would continue , slowly filling the great unwashed with electric cell that did n’t match their genetic constitution . That made sense . scientist had put a new manufacturing center in their patient . It would make what it had always made . It also made a sure , if surprising , sense that cancers that affect blood and os marrow could change a person ’s expressed blood line type as well .
Then an infant with rubella , who has been typed as A many times in the first eight week of her living , all of a sudden miss her A agglutination . At four months sometime , her stock type had actually changed . This may sound eerie to us , but it was effective news to those who require to reverse rake into a fluid that can be donated from anyone to anyone , including to and from one of those 50,000 people in Japan . Anything that could fleece off agglutinations could make every bag of blood into a universal giver udder . It just , sooner , should n’t be rubella .

After years of searching , the best candidate for an agglutination - snipper came from a special mushroom . ( No , not that one . ) An enzyme isolated from fungi was found to turn any stock , any blood at all , to type O , and it did it while the origin was in the cup of tea , not in the patient . This can change pedigree into a fluid that can be given to anyone , and given the shortages at blood bank , anything that made profligate more available to all patients is a good matter . The method is still being tested , but hopefully stock will become a lot more common soon .
But there is still one over-the-top stemma type modification mystery still out there , in the form of what today is a nineteen - year - old girl . As a nine - year - old , the miss ’s liver failed . A transplantation liver was found , and the surgical process was successful . Unfortunately , the girl set about to get sick on the drug that she had to take to pressure her body not to eliminate the new liver . Rejection is a vast business organisation for all bestower . People have to take anti - rejection drugs their whole lives . nauseate immediately when taking them was a very bad foretoken . And then scientist typed her blood . The girl had impromptu modify her lineage , or rather her liver had spontaneously exchange her roue . Stem cells from the liver got to her ivory marrow , and then to her entire immune organisation . Slowly her blood type change from O negative to O electropositive , and her body take the liver . She was taken off the drug , since she did n’t really take them any longer . Doctors called it an one - in - six - billion event . It would be great , for many transplant patients , if someday we could make the betting odds a little better than that .
