Fig. 1From: Microarray profiling shows distinct differences between primary tumors and commonly used preclinical models in hepatocellular carcinomaPCA analysis of hierachial clustering of originating tumors, cell line and xenograft samples. a PC2 versus PC1, b PC3 versus PC2. The originating tumors are represented by spots annotated PTXX. Xenograft and cell lines are segregated from originating tumors. When compared within the murine models, Hep G2 and xenografts from the same primary tumors cluster together regardless of site of implantationBack to article page
