Validation of highly differentially expressed genes in osteosarcoma vs non-malignant bone. Eleven genes were selected at random from Table 1 and validated by PCR in two non-malignant bone samples (lanes 1 and 2), and five randomly selected osteosarcoma patients (lanes 3–7). The results are shown in groups of genes upregulated and downregulated in osteosarcoma compared with non-malignant bone.
