Ingenuity analysis identifies novel gene networks involved in the maintenance of pluripotency. Genes over-expressed in non-human primate embryonic stem cells compared to fibroblasts are depicted in red. Genes shaded in green are over-expressed in fibroblasts. Genes that were differentially expressed in both of two previous studies [1, 117] could be identified in this representative pathway. For this analysis we compared all genes with a known Entrez gene ID.
