A proportion of patients develop poor graft function (PGF) following an allogeneic hemopoietic stem cell transplant (HSCT). In patients with poor graft function (a) a boost of specifically CD34+-selected peripheral blood donor cells is associated with a high chance of trilineage recovery and a low risk of acute GVHD.
