In 1973, 16 HSC transplants (all from bone marrow) were performed in Europe, in 1983 they were 1.353, in 1997 7.7373 and in 1999 17.800, of which 5.733 allogeneic and 12.067 autologous. These data indicate the extraordinary success of HSC transplant and the great potential of this procedure.
Nowadays transplant is offered to a growing number of patients. The types of donors have expanded (from within the same family and allogeneic), the HSC are harvested from different sites (bone marrow, peripheral blood, from umbilical cord blood), the range of usable HSC is wider (hematopoietic but also totipotent stem cells used to cure other illnesses) and also the indications for transplant have changed. In the whole world 10.492 non-consanguineous transplants were performed during 2006.
