What is the merit of an alternative bone marrow transplant?

Bone marrow transplantation has been applied for the treatment of a variety of diseases. There are definite indications for using alternative donors for transplant purposes. Methods to reduce graft-versus-host disease and limit morbidity should be coupled with ways to accelerate immune recovery and decrease infection rates. There is a continued need for workshops to compare data and results so clues will be gained and shared by all as to the indications for transplant, the best approach, and how to limit the short- and long-term morbidity.
