Analysis of percentage change in CD18⁺ and CD18⁻ antineutrophil⁺ and CD14⁺ subsets in the circulation over time. (A) Flow cytometric analysis of the proportion of anti-neutrophil–expressing CD18⁺ and CD18⁻ cells after G-CSF administration in a control dog (C1) and a transplanted dog (T1). (B) Graphic analysis of all 3 transplanted dogs (T1-T3) after G-CSF administration, demonstrating changes in the percentage of CD18⁺ and CD18⁻ anti-neutrophil⁺ and CD14⁺ leukocyte subsets over time.
