The mice were implanted with a human

The current standard for finding organ donors is based on human leukocyte antigen testing. His

used to compare potentialrecipient and donor of a number of proteins on the surface of their cells. They give an idea of ​​how aggressively the recipient's immune system may react to the new organ.

In a new study, scientistsimproved the protocol. They implanted the human immune system into mice. It turns out that the humanized mouse model can be used to evaluate any type of organ transplantation, as well as stem cell transplantation for cancer, autoimmune diseases and other conditions where donor cells are used. The use of model organisms is much faster, safer and more sensitive than the gold standard, scientists report.

So far, the mouse system can only be used for living related donors. However, scientists hope that it will find wider application in the future.
