Immune reconstitution. (A) Patients receiving cryopreserved stem cells (blue bars) had lower WBC and neutrophil count (ANC) at 30 days after transplant compared with patients receiving fresh (red bars) (median WBC 3850 cells per µL vs 6260 cells per µL; P = .0079, median ANC 2240 cells per µL vs 3300 cells per µL; P = .016). There were trends toward lower absolute lymphocyte (ALC) and monocyte (AMC) counts in patients receiving cryopreserved grafts, but these were not statistically significant. (B) Similarly, CD3⁺, CD4⁺ Tcon and Treg, and CD8⁺ subsets also had trends toward lower values in cryopreserved vs fresh.
