Naïve Ground State Reagents from Cell Guidance Systems

Pluripotent mouse and human stem cells behave distinctly. This is not just an interspecies difference, but rather reflects methodology used for isolation and subsequent maintainance. Mouse embryonic stem (ES) cells are said to be in a "naïve" ground state, whereas human ES cells are in a primed state (immediately ready to differentiate towards germ cell layers). These different states can be distinguished in several ways. For example, X chromosome inactivation is not present in the naïve state. There are also important differences in methylation status and transcription factor expression. Compared to primed cells, naïve ground state cells have several desirable characteristics, including ease of maintenance and genetic manipulation. This has lead to a concerted effort by several groups to develop methodology for the derivation and maintenance of naïve ground state human cells which more closely behave like mouse cells. A listing of some of the more recent papers, along with the growth factors and small molecules used  is shown below.
