pubmed:abstractText |
Human osteoclast (OC) formation and activity was studied in cultures of peripheral blood mononuclear cells (PBMNC) from six healthy donors after stimulation with fetal calf serum (FCS), under the influence of the receptor activator of nuclear factor (NF)-kappaB ligand (RANKL) and the macrophage-colony stimulating factor (M-CSF). The results showed that selected FCS could stimulate OC formation without any medium supplementation with osteoclastogenic factors. The OC formation, investigated by quantification of multinucleated tartrate-resistant acid phosphatase-positive cells (TRAP+ cells), and the sensitivity of OC progenitors to RANKL and M-CSF, varied widely between individual donors. The OC resorption activity, measured in the "pit-assay" on dentine, was strictly dependent on the presence of RANKL and M-CSF in the medium and was also donor dependent. The considerable donor variability should be considered in culture studies investigating, e.g. the interactions of OC with biomaterials or the influence of cytokines, growth factors and drugs on osteoclastogenesis.
