In successful haploidentical–cord hematopoietic cell transplantation, the haplo forms a myeloid bridge until cord blood engraftment
Sufficient antithymocyte globulin exposure (area under the curve) after hematopoietic cell transplantation is important for the haplo-myeloid bridge
Without antithymocyte globulin exposure after hematopoietic cell transplantation, both (early) engraftment and hematopoietic cell transplantation outcome are at risk
