Expression of CD166 antigen on human osteosarcoma cell lines. a. The expression of CD166 on four human osteosarcoma cell lines was evaluated by FACS analysis. Saos-2, MG63 cell lines exhibited CD166 expression at high levels, MNNG/HOS, U2OS cell lines exhibited CD166 expression at low levels, respectively (red histograms). For NIH/3 T3 cell lines, CD166 was undetectable. A CD166 isotype antibody was used as a negative control for the detection of CD166 expression (blue histograms). b. The histogram of GD2 expression on NIH/3 T3 and human osteosarcoma cell lines
