Tracking the embryonic stem cell transition from ground state pluripotency

ABSTRACT: Mouse embryonic stem (ES) cells are locked into self-renewal by shielding from inductive cues. Release from this ground state in minimal conditions offers a system for delineating developmental progression from naive pluripotency. Here we examined the initial transition process. The ES cell population behaves asynchronously. We therefore exploited a short-half-life Rex1::GFP reporter to isolate cells either side of exit from naive status. Differentiation of Rex1-GFPd2 ES cells was initiated by withdrawing 2i (Kalkan et al., 2016). Undifferentiated 2i-cells and post-2i withdrawal differentiating populations (16h, 25h-Rex1-High, 25h-Rex1-Low) were subjected to proteomic analysis by Mass Spectrometry.

Mouse embryonic stem (ES) cells are locked into self-renewal by shielding from inductive cues. Release from this ground state in minimal conditions offers a system for delineating developmental progression from naïve pluripotency. Here, we examine the initial transition process. The ES cell population behaves asynchronously. We therefore exploited a short-half-life <i>Rex1::GFP</i> reporter to isolate cells either side of exit from naïve status.
