The nature of embryonic stem cells.

Mouse embryonic stem (ES) cells perpetuate in vitro the broad developmental potential of naïve founder cells in the preimplantation embryo. ES cells self-renew relentlessly in culture but can reenter embryonic development seamlessly, differentiating on schedule to form all elements of the fetus. Here we review the properties of these remarkable cells. Arising from the stability, homogeneity, and equipotency of ES cells, we consider the concept of a pluripotent ground state. We evaluate the authenticity of ES cells in relation to cells in the embryo and examine their utility for dissecting mechanisms that confer pluripotency and that execute fate choice. We summarize current knowledge of the transcription factor circuitry that governs the ES cell state and discuss the opportunity to expose molecular logic further through iterative computational modeling and experimentation. Finally, we present a perspective on unresolved questions, including the challenge of deriving ground state pluripotent stem cells from non-rodent species.
