CD14 and acute lymphoblastic leukemia: We observed significantly higher frequencies of putative proangiogenic intermediate monocytes (delineated by CD14++CD16+ phenotype, Figure 3(a)), but not nonclassical CD14+CD16++ monocytes (Figure 3(b)) in G-CSF-treated ALL patients as compared to normal donors (16.10 (11.90–22.10) versus 5.86 (4.54–9.35)).
