Cell Line Origin
Mouse embryonic stem cell
Cell Line Description
The germ-line competent cell line MESC 17 was established from the inner cell mass of a 3.5 day female pre-implantation mouse embryo (strain C57BL/6J). These pluripotent cells retain the ability to participate in normal embryonic development.

Culture Medium
MEF medium consists of Advanced DMEM/F12 (Invitrogen 12634010), 10% FBS (Perbio SH30070.03E), 2 mM Glutamine (Invitrogen 25030024) and 0.1 mM β-mercaptoethanol (Sigma product number M6250). KSR medium consists of KO-DMEM (Gibco 10829), 20% Knock-Out Serum Replacer (Gibco 10828), 2 mM Glutamine (Invitrogen 25030024), NEAA (Invitrogen 11140035), 0.1 mM β-mercaptoethanol (Sigma product number M6250) and LIF 1000 Units/ml (ESGRO ESG1106).
Subculture Routine
The MESC lines can be grown without the use of mitotically inactivated feeder cells (Brown et al., 1992 PMID: 1483967). However, the cells supplied by ECACC have been grown on mitomycin treated primary mouse embryonic fibroblasts to ensure the cells are maintained in an undifferentiated state. Mouse embryonic fibroblasts, STO (Sigma product number 86032003) or SNL 76/7 (Sigma product number 07032801) can be used. At ECACC plastic ware is pre-coated with gelatine prior to plating feeder cells.
Porcine gelatine (Sigma G1890) is dissolved in sterile water (0.5 g/500ml) at 56 °C. The 0.1% solution is sterilized by filtration (0.22 μm). Add 0.1% gelatine to plastic ware to cover bottom, and incubate for 20 min at room temperature. Remove gelatine, wash with PBS once and replace with appropriate culture medium. The flask/dish must not be allowed to dry out.
Feeder layers are prepared on the gelatinized flasks at least 24 h in advance of being required. An ampoule is thawed in 37 °C water bath and the contents quickly transferred to a 15 ml centrifuge tube. MEF medium is added drop wise to 5 ml. Cells are centrifuged at 150 x g for 5 min at room temperature. Cells are resuspended in 5 ml of MEF medium. Cells are counted and added to flasks containing the correct medium at 1-3 x 104 cells/cm2.
An ampoule of ES cells is thawed in 37 °C water bath and the contents quickly transferred to a 15 ml centrifuge tube. KSR medium is added drop wise to 5 ml. Cells are centrifuged at 150 x g for 5 min. Cells are resuspended in 5 ml of KSR medium. The prepared feeder flask is washed once with PBS and KSR medium added. ES cells should be plated at 4-5 x 104 cells/cm2. Cultures must be incubated in a humidified 5% CO2/95% air incubator at 37 °C. A 100% media change must be performed every day and cells passaged every 2-3 days. Colonies must not be allowed to touch each other as overgrowth will result in differentiation.
