Planarian stem cell transcriptome

ABSTRACT: Many long-lived species of animals require the function of adult stem cells throughout their lives. However, the transcriptomes of stem cells in invertebrates and vertebrates have not been compared, and consequently ancestral regulatory circuits that control stem cell populations remain poorly defined. In this study, we have used data from high-throughput RNA sequencing (RNA-Seq) to compare the transcriptomes of pluripotent adult stem cells from planarians with the transcriptomes of human and mouse pluripotent embryonic stem cells. From a stringently-defined set of 4,432 orthologs shared between planarians, mice and humans, we identified 123 conserved genes that are ≥ 5-fold differentially expressed in stem cells from all three species. Guided by this gene set, we used RNAi screening i
