Source: Organ: testis

Strain: 129

Cellular Products: plasminogen activator; laminin; type IV collagen

Permits/Forms: In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimay responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.

Applications: transfection host （Roche FuGENE® Transfection Reagents）

Age:  embryo

Comments: F9 cells can be stimulated to differentiate into parietal endoderm in the presence of retinoic acid and dibutyryl cyclic AMP （cAMP）.

Differentiating cells synthesize plasminogen activator, laminin and type IV collagen.

cAMP is active only on cells that have been treated with retinoic acid.

The cells maintain three copies of the beta 1 integrin gene.

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: fetal bovine serum to a final concentration of 10%.

Temperature: 37.0°C

Subculturing:  Protocol: NOTE: culture vessels must be coated with 0.1% gelatin prior to use.To do so, cover the surface of the vessel with 0.1% gelatin （Difco） in sterile distilled water for 2 hours at 4C, then wash three times with sterile distilled water. Treated flasks and dishes can be stored at room temperature.

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 appropriate aliquots of the cell suspension to new coated culture vessels.

Incubate cultures at 37°C.

Subc*tion Ratio: A subc*tion ratio of 1:10 is recommended

Medium Renewal: Every 2 to 3 days

Related Products: Recommended medium （without the additional supplements or serum described under ATCC Medium）:ATCC 30-2002

recommended serum:ATCC 30-2020
