Figure 1From: Profiling of pathway-specific changes in gene expression following growth of human cancer cell lines transplanted into micePrincipal components analysis (PCA) plot of global gene-expression profiles from cell cultures, xenografts, and human lung and brain tumors. Principal components were extracted from the cell culture and xenograft expression data (but not the lung and brain tumor data) using all 7,029 HuGeneFL probe sets. The first two principal components are shown.Back to article page
