Comparison of the number of PKH26+ marrow cells detected in (A) FR25Lin− and (B) R/O fractions at different times posttransplant. These series of dot plots represent the flow diagrams of FR25Lin− (A) and R/O (B) frequencies of PKH-labeled cells present before (0 hours) and various times posttransplant of 2.5 × 106 cells. The number at the top right of each panel represents the percentage frequency of PKH bright cells detected. All plots represent equal numbers of cells counted (100,000).
