Age: embryo, blastocyst
Comments: The cells spontaneously differentiate into embryonic structures in the absence of a feeder layer or conditioned medium. They can be injected back into blastocysts and contribute to the germline. Undifferentiated cells can be genetically modified by gene targeting techniques.
Propagation: ES-D3細胞ATCC complete growth medium: Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and 4.5 g/L glucose supplemented with 0.1 mM 2-mercaptoethanol, 85%; heat-inactivated fetal bovine serum, 15%
Temperature: 37.0°C
Subculturing: Protocol: Note: The cells can be maintained in the undifferentiated state by frequent subculture on feeder layers of irradiated (3000 rads) or mitomycin C treated (0.01 mg/ml for 90 minutes) primary mouse embryonic fibroblasts or STO cells (see ATCC CRL-1503, STO or ATCC 56-X, irradiated STO cells).
Remove and discard culture medium.
Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37?C to facilitate dispersal.
Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
Add fresh medium, aspirate and dispense onto fresh feeder layer cultures.
Incubate cultures at 37?C.
