Just when you think you have got everything under control and you know how the human body works (well more or less) it goes and does something completely unexpected and stumps you. In this case a 15 year old girl switched her blood type.
This Australian girl was seriously ill and suffering from a failed liver when she underwent a liver transplant at a top Sydney children’s hospital. Nine months later they found out that her immune system had switched over to that of the donor. This happened when stem cells from her new liver migrated to her bone marrow, and thus changed her blood type.
Apparently this is the only known case so far and the hepatologist treating her, Michael Stormon is quoted as saying “It is extremely unusual — in fact we don’t know of any other instance in which this happened,”
This just goes to show that we really have no idea what’s going on inside us do we?
