Process And Procedural Adjustments To Improve Cd34+Collection Efficiency Of Hematopoietic Progenitor Cell Collections In Sickle Cell Disease

Adjustments to the HPC collection process and procedure were associated with adequate CD34+ CEs and low granulocyte and platelet contamination in HPC products from SCD patients. Given the discrepancy in the percentage of sickle RBCs in the product versus the PB, we hypothesize that CD34+ cells and RBCs may aggregate. Our interventions and hypothesis should be further investigated in larger studies.
