The
number of patients waiting for a transplant organ by far exceeds
the number of organs available. In the U.S. alone, over 100,000
patients are waiting for an organ, but less than a third will receive
an organ this year: an estimated 28,000 organs are transplanted
annually as the treatment of choice for organ failure [1]. Organ shortage
is a global problem: at the end of 2008, over 61,000 patients were
recorded on the transplant waiting list in the European Union (EU) and
over 35,000 patients had been admitted to waiting lists outside the
U.S. and EU [2].
