Effect of nucleated cell count and cryopreservation on engraftment post autologous stem cell transplant.

Using 753 collections from 426 adult haematology patients, we conducted a retrospective, analysis into the effects of overnight storage and nucleated cell counts (NCC) on viable, CD34 (vCD34) recovery and engraftment kinetics post autologous stem cell, transplant (ASCT) with peripheral blood stem cells (PBSC). There were significant, differences in vCD34 + recovery ( P < 0.01) after cryopreservation associated with, the fresh NCC of ≥ 300 × 10 /mL in products stored overnight, but no association, with time to platelet or neutrophil engraftment post-ASCT was observed for these, products.
