Alpha/Beta T-Zell-depletierte Blutbildende Stammzelltransplantation von verwandten oder nicht verwandten Spendern für Blutkrankheiten bei Kindern und jungen Erwachsenen

Kurzzusammenfassung

This study is being done to see if the investigators can take peripheral blood stem cells from either an adult family member or a closely matched unrelated donor, and run them through a special lab instrument to remove alpha/beta T cells and B cells and then give them to the patient to treat disease. This is an experimental way of doing a hematopoietic stem cell transplant (HSCT). The investigators want to see if the new stem cells will grow without bad graft vs. host disease (GVHD). This treatment approach is experimental in the United States.
