Circulating CFCs and LTC-ICs. Peak values (A,C) and box plots (B,D) of CFCs and LTC-ICs per milliliter of blood in poor mobilizers receiving rhG-CSF (n = 16) or rhGH/rhG-CSF (n = 16). CFCs include CFU-GMs, BFU-Es, and CFU-Mix. Peaks of CFCs and LTC-ICs were defined as the maximum numbers of CFCs or LTC-ICs detected in the peripheral blood during mobilization. The boxes extend from the 25th percentile to the 75th percentile, the lines indicate the median values, and the whiskers indicate the range of values. Statistical difference was evaluated using the Wilcoxon matched pairs test (2-tail). Numbers in the panels (B,D) indicate P values.
