Figure 2 Flow cytometry analysis of mobilized stem cells at baseline and 5 days after initiation of granulocyte colony-stimulating factor (G-CSF). CD34⁺ stem cell populations from peripheral blood measured by flow cytometry. (A) Quantitative measurements of CD34⁺/CD31⁺, CD34⁺/133⁺, and CD34⁺/CD117⁺ cells in placebo and G-CSF-treated patients before and at day 5 of treatment. *p < 0.001; **p < 0.001; ***p < 0.001 when compared with placebo at day 5. (B) The R4 population demonstrates increases of precursor cells in a representative patient before and at day 5 of treatment with G-CSF.
