Abstract

Summary: Nanog is a core transcription factor specifically expressed not only in the pluripotent stem cells (PSCs), such as embryonic stem cells (ESCs), embryonic germ cells (EGCs), and induced PSCs (iPSCs), but also in the unipotent primordial germ cells (PGCs). Although Nanog promoter/enhancer regions are well characterized by in vitro analyses, direct correlations between the regulatory elements for Nanog expression and in vivo expression patterns of Nanog have not been fully clarified. In this study, we generated Nanog ‐RFP transgenic (Tg) mice in which expression of red fluorescent protein (RFP) is driven by a 5.2 kb Nanog promoter/enhancer region. As expected, RFP was expressed in the inner cell mass of blastocysts, ESCs, and iPSCs. However, RFP fluorescence was not observed in PGCs, although Nanog was expressed in PGCs. Because RFP fluorescence was visible in the PGC‐derived pluripotent EGCs in culture, it was suggested that the reporter gene expression was specifically activated in PSCs. In conclusion, we have generated a novel Nanog ‐RFP Tg mouse line that can selectively tag PSCs over unipotent PGCs.
