Global Gene Expression Profiling of Human Osteosarcomas Reveals Metastasis-Associated Chemokine Pattern
Figure 3
Relative CXCR4 expression in primary tumours from patients who did or did not develop metastases and in metastatic samples (one primary tumour with no clinical information on metastases was excluded) based on (a) microarray data and (b) quantitative real-time RT-PCR data. For the quantitative real-time RT-PCR data, the expression levels have been normalised to the average expression of three housekeeping genes (18S, B2M and TBP) and compared to the average expression of two normal bone samples. The average expression level in each sample group is indicated with a black bar. NA, not available.
