The histology of the xenografts derived from the transduced and parental MG-63 cells. a–c Representative images of immunofluorescence analysis (left panel). The tumors derived from MG-OKS were positive for Ki-67, osteocalcin, and HIF-1α (red). Nuclei were stained with blue fluorescent DAPI. Positive areas were assessed by software, 4 fields were randomly selected, and means were calculated (right panel). Scale bars 100 μm. The error bars indicate the standard error of the mean: SEM. *P < 0.05
