In the present study, we showed that CD14+ adherent human monocytes can differentiate into CD1+relB+ dendritic cells ( DC ) by the combination of GM-CSF plus interleukin-4 ( IL-4 ) and that they differentiate into tartrate-resistant acid phosphatase (TRAP)-positive osteoclast-like multinucleated giant cells ( MGC ) by the combination of M-CSF plus IL-4 .
 MGC, CD1+relB+ dendritic cells, human monocytes, tartrate-resistant acid phosphatase (TRAP)-positive osteoclast-like multinucleated giant cells, M-CSF, interleukin-4, IL-4, CD14+ adherent human monocytes, DC, GM-CSF, IL-4
