Changes in CD4+ lymphocyte HIV-1 DNA during mobilization and harvesting of stem cells for individual subjects.

(A) Cohort 1. (B) Cohort 2. (C) Cohort 3. (vertical dotted lines) Granulocyte colony-stimulating factor was administered on days 1 through 7. (arrows) Leukapheresis was performed on days 4 and 5. For subject 620 733 in cohort 1 and subject 061 144 in cohort 3, day-27 peripheral blood mononuclear cells samples were unavailable. The levels of CD4+ lymphocyte HIV-1 DNA for subject 061 146 was below the limit of detection at all time points and are not shown.
