Abstrakt: Aim:Delayed platelet reconstitution in the peripheral blood (PB) remains a problem in transplantation with umbilical cord blood (CB)-derived stem cells. Previously, we have shown that transplantation with ex-vivo expanded CB CD34+cells (CD34exp) with thrombopoietin for 10 days, results in an accelerated platelet reconstitution in NOD/SCID mice. It has been shown that mesenchymal stem cells (MSC) are able to enhance the overall engraftment when co-transplanted with CB CD34+cells. Therefore, we investigated whether co-transplantation of MSC with CD34+cells or CD34expcells may have an additive effect in shortening the time to platelet recovery and on the total number of platelets in the PB at 6 weeks after transplantation.
