Identification of differentially expressed circRNA profiles. Differentially expressed circRNAs between CD90+ and CD90− cells were analyzed using a high throughput microarray assay. (A) The heat map revealed 274 distinguishable (238 upregulated and 36 downregulated) circRNAs with differential expression between CD90+ and CD90− cells. (B) The key signaling pathways for these circRNAs were identified by Kyoto Encyclopedia of Genes and Genomes enrichment analyses and the top 20 are listed; the top three signaling pathways were the metabolic pathway, pathways in cancer, and the P13K-AKT signaling pathway. CD, cluster of differentiation; circRNA, circular RNA; P13K-AKT, phosphoinositide 3-kinase (P13K)-RAC-α serine/threonine-protein kinase.
