Lack of or severe reduction of Rh blood group antigens. The Rh-null blood type predominantly arises due to lack of Rh blood group antigens, or when the Rh antigens decrease severely. Blood from these patients does not react with antiseras. R-null cells lack Rh polypeptides and are deficient in Rh-associated glycoprotein and glycophorin. 8.Blood types are a classification of blood based on the antigens present in red blood cells. In the United States, O-positive is the most common blood type, ...The Rh blood group system consists of 49 defined blood group antigens. One of them is the D antigen. If you test negative for the presence of the D antigen, you are Rh Negative. This is why Rh Negative is also often listed as Rh(D) negative or D negative.

Rh Blood Group System. The Rh (rhesus) system was first recognized in 1939 and defined as D in 1940. The antibody produced by guinea pigs and rabbits in response to rhesus monkey cells agglutinated 85% of human RBCs. This was called anti-Rhesus, and the corresponding human antigen was called Rhesus.

Here, we present a CRISPR/Cas9-mediated ABO gene edition strategy for the conversion of blood type A to universal type O, which we have applied to an Rh null donor-derived hiPSC line, originally carrying blood group A.
