Percentage of HSC, FC, and CD8⁺ T cells in PB during treatment with (A) FL alone (n = 5), (B) G-CSF alone (n = 5), or (C) FL + G-CSF (n = 5). FL (10 μg/mouse) was injected SC from day 1 to 10 and G-CSF (7.5 μg/mouse) from day 4 to 10. PB was stained for HSC (▪) (lineage⁻/Sca-1⁺/c-kit⁺), FC (□) (CD8⁺/βTCR⁻/γδTCR⁻), and CD8⁺ T cells (▧) (CD8⁺/βTCR⁺). Results show the mean (SEM) percentage before and on day 7 and day 10 of growth factor administration. Percentages of HSC, FC, or CD8⁺ T cells that differed significantly from day 0 values are marked (* P< .05; ** P < .005; or *** P < .0005).
