Pediatric hematopoietic stem cell transplantation

The successful use of allogeneic HSCT for children with malignant and nonmalignant diseases continues to be limited by the development of acute and chronic GVHD, infectious complications, delayed recovery of the immune system, acute and long-term toxicity and relapse of disease. Significant advances have been made, particularly in the ability to identify suitable sources of HSC. Future advances will depend on a better understanding of the biology of HSC sources, GVHD, immune reconstitution, and common complications. Improved therapies are dependent on participation of children in well-designed, translational and clinical transplant studies.
