Derivation UMNSAH/DF-1 is a spontaneously immortalized chicken cell line derived from 10 day old East Lansing Line (ELL-0) eggs.
Primary chicken embryonic fibroblasts were dissociated and grown in culture; the fibroblasts were passaged until they began to senesce; the cells were concentrated during cell senescence to maintain about 30% to about 60% culture confluence.
Tumorigenic No
Effects No, in immunosuppressed mice
No, in semisolid medium
Virus Susceptibility Meleagrid herpesvirus 1
Fowlpox virus
Avian reovirus
Rous sarcoma virus
Comments foci of non-senescent cells were identified and grown for greater than 30 passages.
No clonal proliferation was observed in soft agar cultures, indicating that these cells were immortalized but not transformed.
Complete Growth Medium The base medium for this cell line is Dulbecco's Modified Eagle's Medium. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
1. Remove and discard culture medium.
2. 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.
3. 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 39°C to facilitate dispersal.
4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
5. Add appropriate aliquots of the cell suspension to new culture vessels.
6. Incubate cultures at 39°C.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:10 is recommended
Medium Renewal: Twice per week
Cryopreservation Freeze medium: Complete growth medium supplemented with 5% DMSO
Storage temperature: liquid nitrogen vapor phase
Culture Conditions Temperature: 39°C; (Max. 40°C, Min. 38°C)
