circular RNA (circRNA) expression profile in intestinal stem cells

Purpose: circRNAs emerge as critical modulators in various biogical processes, but their roles in intestinal stem cells (ISC) reamin unclear. Here we want to identify a functional circRNA in ISCs, and firstly, we explore the expression profile of circRNA in ISCs. Methods: We isolated Lgr5+ ISCs and Lgr5- non-ISCs from the intestine tissue, followed by circRNA seq. Results: Many circRNAs are differently expressed in ISCs and non-ISCs, and we selected circRNAs highly expressed in ISCs for further investigation. Conclusions: circRNAs may play a critical role in ISC self-renewal. Examination of circRNA expression in 2 ISCs and non-ISCs.
