Conserved genes and pathways across the human and mouse mammary stem cell-enriched subsets. Ingenuity pathway analysis of conserved genes between mouse and human, and mouse genes with human orthologues, in the MaSC-enriched subset. The genes are divided according to the cellular distribution of the proteins for which they encode. The active pathways in each subset are represented on the right. Red represents upregulated genes, whereas green depicts downregulated genes. White symbols depict neighboring genes. The intensity of color represents the average log fold-change in a given population relative to the other epithelial subsets.
