Improving the outcome of unrelated donor stem cell transplantation by molecular matching.
Volunteer unrelated donor (VUD) stem cell transplantation is now a well-established procedure in the treatment for many haematological and other disorders. The improved success of this modality of treatment is related, in part, to the existence of large volunteer donor registries (with well characterized tissue typing), as well as to the improved understanding of the molecular factors that have an influence on transplantation outcome. It is clear that close attention to human leukocyte antigen (HLA) matching is essential in ensuring a satisfactory transplant outcome, however the extent to which donor-recipient pairs need to be matched is not yet clear. There is also an increased understanding that factors other than HLA do affect clinical outcome. The ability to perform high resolution molecular typing techniques has allowed researchers to begin assessing the significance of mismatches at particular loci against an otherwise matched background, and in this way highlight the effects of individual genetic factors on transplantation outcome.
