  • Title: Culture of mouse embryonic stem cells.
    Author: Tremml G, Singer M, Malavarca R.
    Journal: Curr Protoc Stem Cell Biol; 2008 Apr; Chapter 1():Unit 1C.4. PubMed ID: 18770628.
    Abstract:
    In this unit standard culture conditions for mouse embryonic stem cells (mESCs) on primary murine embryonic fibroblast (PMEF or MEF) monolayers, culture conditions without MEF for feeder-independent mESCs, and culture conditions in chemically defined media for both feeder-independent mESCs and feeder-dependent mESCs are described. For expansion of an mESC line, it is crucial that cells maintain their undifferentiated state and their self-renewal capacity, and that they remain karyotypically normal, all of which are necessary for successful chimerization of the germ line upon blastocyst injection. Derivation and culture conditions for the original mESCs have been described (notably Robertson, 1987; Smith, 1991; Nagy et al., 2003), however, as there are more and more mESC lines available, it becomes evident that culture conditions are cell-line specific to some extent, and there is a constant demand for culturing details for mESC lines derived from different mouse strains.
