Figure 1From: Conservation of core gene expression in vertebrate tissuesComparison of tissue expression profiles among five diverse vertebrates. Clustered heat map of the all-versus-all Pearson correlation matrix between 20 tissues in each of human (H), mouse (M), chicken (C), frog (F) and pufferfish (P) over all 3,074 1-1-1-1-1 orthologs. Analogous and functionally related tissues are boxed in white, demonstrating the cross-species similarity of those tissues on the basis of their gene expression profiles.Back to article page
