Dominant unit CD 34 1 cell dose predicts engraftment after double-unit cord blood transplantation and is in fl uenced by bank practice

1480%.Notably, units fromnon–NetcordFoundation for theAccreditationofCellular Therapy (Netcord-FACT)–accreditedbankswere more likely to have low recovery (P < .001). Furthermore, although median postthaw CD34 cell viability was 92%, 33 (8%) units had <75%viableCD34cells.Units fromnon–Netcord-FACT–accreditedbanksandunitswithcryovolumesother than24.5 to26.0mLwere more likely to have poor postthaw viability. Precryopreservation CD34 cell dose and banking practices should be incorporated into
