| Age |
6 weeks |
| Gender |
female |
| Strain |
BALB/c |
| Applications |
The line is a good transfection recipient for assaying the function of genetic regulatory sequences for various liver genes that do not function in other hepatocyte-derived cell lines. This cell line provides a model system for studying hepatocyte differentiation in which various hepatocyte phenotypes are inducible. |
| Storage Conditions |
liquid nitrogen vapor phase |
| Derivation |
H2.35 cells were cloned from a colony that arose from the SV40 transformed cells. H2.35 is an epithelial-like cell line derived from a primary hepatocyte culture. Cells were collected from the livers of 6 week old female BALB/c mice, incubated at 33°C, and infected with tsA255 (a temperature-sensitive mutant of SV40 virus). |
| Clinical Data |
Cells were collected from the livers of 6 week old female BALB/c mice, incubated at 33°C, and infected with tsA255 (a temperature-sensitive mutant of SV40 virus).
female |
| Tumorigenic |
Yes |
| Effects |
Yes, in BALB/c nu/nu mice |
| Virus Susceptibility |
Semliki Forest virus
|
| Comments |
The cells undergo morphological changes in response to extracellular matrix gel substrata, and albumin gene transcription is induced. Culturing the cells in serum-free medium and on collagen gels causes the induction of several liver enriched transcription factors. |
| Complete Growth Medium |
Dulbecco's modified Eagle's medium with 1.0 g/L glucose and 200 nM dexamethasone, 96.0%; fetal bovine serum, 4.0%
|
| Subculturing |
- Remove and discard culture medium.
- Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.03% 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 33°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 culture vessels.
Incubate cultures at 33°C.
Subcultivation Ratio: A subcultivation ratio of 1:6 to 1:10 is recommended Medium Renewal: 2 to 3 times per week |
| Cryopreservation |
Freeze medium: Complete growth medium supplemented with an additional 20% fetal bovine serum and 5% DMSO Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions |
Atmosphere: air, 90%; carbon dioxide (CO2), 10% Temperature: 33°C |
| Temperature Effects |
Restrictive temperature: 39° C expresses 100-fold higher levels of albumin mRNA Permissive temperature: 33°C express only very low levels of albumin mRNA The cells are temperature sensitive for the expression of serum albumin mRNA. |

The cells are temperature sensitive for the expression of serum albumin mRNA.
Expression of albumin mRNA requires growth on serum-free medium and collagen-coated surface.
