Figure 1. Immune reconstitution following umbilical cord blood
transplantation (UCBT). A . Time frame of immune recovery is
depicted in this illustration. TREC (T cell receptor excision circles)
presented in cells/mcL; STR (short tandem repeat) in percent values; PHA
(Phytohemagglutinin); PWM (Pokeweed); Con A (Concanavalin A).B . Post-UCBT immune reconstitution course of T cells (CD3+),
recent thymic emigrants (RTE) that are CD3+CD4+CD45RA+CD31+, CD5-dim T
cells, CD4+ T cells and CD8+ T cells in percent values of the
denominator population. Higher CD5-dim T cell ratios in earlier days of
immune reconstitution may reflect greater release of maturing thymocytes
into circulation. C . Flow cytometry histograms reflecting the
pattern of CD3+/CD4+ cells, RTE, CD56+/CD16+/– cells and CD5-dim T
cells (all gated on lymphocyte population) 10 months following UCBT.
