Human Myeloma Cell Lines Induce Osteoblast Downregulation of CD99 Which Is Involved in Osteoblast Formation and Activity

Figure 8

CD99 agonist monoclonal antibody does not induce the reduction of normal human osteoblast (hOBs) viability. Cell viability, evaluated by MTT assay, in hOBs treated for 24 or 48 h with anti-CD99 agonist monoclonal antibody. Results are expressed as values of optical density at 570 nm ± SE of three independent experiments performed in triplicate.
