Dynamics of percentages of distinct plasmacytoid and myeloid DC precursors in patients treated or untreated with G-CSF after Allo-HSCT. Median values with interquartiles (error bars) were obtained from patients without evidence of GVHD or any other major complication. Data from a group of 12 patients treated with G-CSF (•) and from a group of 14 untreated patients (○) are shown. Data were compared by nonparametric Mann-Whitney test. *P < .05 was considered. Also, data from 10 age-matched healthy subjects and from 15 patients of each group obtained before Allo-HSCT are shown as □ and ▪ on the left side of each graph, respectively.
