1 Recombinant Human Granulocyte Colony-Stimulating Factor Significantly Decreases the Expression of CXCR3 and CCR6 on T Cells and Preferentially Induces T helper Cells to a T helper 17 Phenotype in Peripheral Blood Harvests  Li-Xia Sun, Han-Yun Ren, Yong-Jin Shi, Li-Hong Wang, Zhi-Xiang Qiu  Biology of Blood and Marrow Transplantation  Volume 15, Issue 7, Pages (July 2009) DOI: /j.bbmt Copyright © 2009 American Society for Blood and Marrow Transplantation Terms and Conditions

2 Figure 1 CXCR3 expression on T cells in rhG-CSF-mobilized PBSC grafts (light symbols) and SS-PB (dark symbols). Mean values are represented by horizontal lines in each series. (A) Representative example of CXCR3 expression on CD3+, CD4+, and CD8+ T cells in SS-PB and PBSC grafts. (B) Percentages of CXCR3 expression on CD3+, CD4+, and CD8+ T cells before and after in vivo rhG-CSF application.

3 Figure 2 CCR6 expression on T cells in rhG-CSF-mobilized PBSC grafts (light symbols) and SS-PB (dark symbols). Mean values are represented by horizontal lines in each series. (A) Representative example of CCR6 expression on CD3+, CD4+, and CD8+ T cells in SS-PB and PBSC grafts. (B) Percentages of CCR6 expression on CD3+, CD4+, and CD8+ T cells before and after in vivo rhG-CSF application.

4 Figure 3 Effect of rhG-CSF on IFN-γ, IL-4, and IL-17 production by CD4+ Th cells. Bars represent percentages (mean ± SD) in IFN-γ-, IL-4-, and IL-17–expressing CD4+ Th cells before (light bars) and after (black bars) rhG-CSF mobilization. P values were determined using t-tests for paired samples. ∗P < .01, ∗∗P < .05. (A) Mean percentages of IFN-γ-, IL-4-, and IL-17-producing CD4+ Th cells. (B) Representative example of IL-17-producing CD4+ T cells before and after rhG-CSF application.
