Figure 1. Lymphocytes and Lymphocyte Subsets after Infusion of Autologous Lentiviral-Transduced CD34+ Cells.

Shown are cells per cubic millimeter of peripheral blood. The values that were used to define T-cell immune reconstitution (dashed lines) are as follows: CD3 T cells, more than 1000 per cubic millimeter; CD4 T cells, more than 500 per cubic millimeter; CD8 T cells, more than 300 per cubic millimeter; and naive CD4 T cells, more than 200 per cubic millimeter.^7,13 The mean number of regulatory T cells for children 10 to 48 months of age is 60 per cubic millimeter (range, not available).²³
