The pluripotency of embryonic stem cells (ESCs) is controlled by a multilayer regulatory network, of which the key factors include core pluripotency genes and , and multiple microRNAs (miRNAs). Recently, long noncoding RNAs (lncRNAs) have been discovered as a class of new regulators for ESCs, and some lncRNAs could function as competing endogenous RNAs (ceRNAs) to regulate mRNAs by competitively binding to miRNAs. Here, we identify mmu-miR-139-5p as a new regulator for by targeting 3' untranslated region (UTR) to repress expression in mouse ESCs and embryos. Such regulation could be released by an ESC-specifically expressed ceRNA named . The expression of is activated by OCT4, SOX2, as well as NANOG through promoter binding. Downregulation of reduces abundance, which leads to decreased pluripotency of mouse ESCs and embryonic lethality. These results reveal as a new regulator for in mouse ESCs, and uncover a feed-forward regulatory loop of through the participation of .
