Molecular Characterization of Putative Chordoma Cell Lines

Figure 3

Gene expression analysis of chordoma tumors, cell lines, and mesenchymal tumors. Five chordoma-specific genes from among the 1208 probe sets used for cluster analysis are included; T: brachyury, KRT19: keratin19, Col2A1: collagen 2A1, CA3: carbonic anhydrase 3, and CD24. Genes with decreased relative expression are shown in green while those with increased relative expression are shown in red. Chordoma tumors (chordoma and chordoma-MK) and cell lines U-CH1, U-CH2, and K001 have a similar expression patterns distinct from the other putative chordoma cell lines and other tissues.
