細胞系描述
Pluripotent mouse embryonic stem cell line. R1 ES cells were established in August 1991 from a male blastocyst hybrid of two 129 substrains (129X1/SvJ and 129S1/SV-+p+Tyr-c Kitl Sl-J/+).
培養基
MEF medium consists of Advanced DMEM/F12 (Invitrogen 12634010), 10% FBS (Perbio SH30070.03E), 2 mM Glutamine (Invitrogen 25030024) and 0.1 mM ß-mercaptoethanol (Sigma 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 ß-mercaptoethanol (Sigma M6250) and LIF 1000 Units/ml (ESGRO ESG1106).

Embryonic stem (ES) cells require the use of mitotically inactivated feeder cells to support the growth of stem cells in the undifferentiated state. Mouse embryonic fibroblasts, STO (Sigma catalog no. 86032003) or SNL 76/7 (Sigma catalog no. 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/500 ml) 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 minutes 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 hours 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 minutes at room temperature (RT). 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 minutes. 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.

Several newly generated mouse embryonic stem (ES) cell lines were tested for their ability to produce completely ES cell-derived mice at early passage numbers by ES cell <==> tetraploid embryo aggregation. One line, designated R1, produced live offspring which were

Since the technique of introducing a targeted mutation ('gene targeting') into the mouse genome was published almost 20 years ago (Cell 51:503-512, 1987), the number of mouse mutants (mouse models) is increasing, especially after the advent of the full mouse
