Comments: This is a derivative of one of several embryonal stem cell (ES) lines developed by M. Hooper in 1987.
The cells are deficient in HGPRT (HPRT) and are resistant to 0.06 mM 6-thioguanine.
The cells remain undifferentiated when cultured on feeder layers (embryonic fibroblasts or STO cells).
The cells spontaneously differentiate and form embryonal structures in the absence of a feeder layer.
When injected into blastocysts, the cells can colonize the germline.
After conventional molecular gene modification techniques, they may be used to reconstitute mouse embryos.
They may also be of use in studies of early post implantation structures.
Tested and found negative for ectromelia virus (mousepox).
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: 2-mercaptoethanol to a final concentration of 0.1 mM ; fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Subculturing: Protocol: ES-E14TG2a細(xì)胞Remove medium, add fresh 0.25% trypsin, 0.53mM EDTA solution. Allow the trypsin to loosen the cells, add fresh medium, aspirate and dispense into new flasks containing pre-plated irradiated feeder cells.
Subcultivation Ratio: A subcultivation ratio of 1:5 is recommended
