Karyotype near diploid RefPfeifer AM, et al. Simian virus 40 large tumor antigen-immortalized normal human liver epithelial cells express hepatocyte characteristics and metabolize chemical carcinogens. Proc. Natl. Acad. Sci. USA 90: 5123-5127, 1993. PubMed: 7685115
Derivation
The THLE-2 (ATCC CRL-10149 and the THLE-3 (ATCC CRL-11233) cell lines were derived from primary normal liver cells by infection with SV40 large T antigen.
Genes Expressed
The cells express cytokeratin 18 and albumin in early passage, whereas higher-passage cells in logarithmic-phase growth also express cytokeratin 19.
Cellular Products
The cells express cytokeratin 18 and albumin in early passage, whereas higher-passage cells in logarithmic-phase growth also express cytokeratin 19.
Tumorigenic NO
Effects
No, in nude mice
Comments

The virus was generated by introducing a retroviral vector containing the of Bgl I-Hpa I fragment of SV40 T antigen into the amphotropic packaging cell line PA317.

THLE-2 and THLE-3 cells express phenotypic characteristics of normal adult liver epithelial cells. They are nontumorigenic when injected into athymic nude mice, have near-diploid karyotypes, and do not express alpha-fetoprotein.

THLE-2 and THLE-3 cells metabolize benzo[a]pyrene, N-nitrosodimethylamine, and aflatoxin B1 to their ultimate carcinogenic metabolites that adduct DNA, which indicates functional cytochrome P450 pathways.

Other enzymes involved in metabolism of chemical carcinogens, such as epoxide hydrolase, NADPH cytochrome P450 reductase, superoxide dismutase, catalase, glutathione S-transferases, and glutathione peroxidase are also retained by THLE cells.

A culture submitted to the ATCC in January of 1993 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with mycoplasma removal agent (MRA).

The cells were assayed for mycoplasma, by the Hoechst stain, PCR and the standard culture test, after a six-week period following treatment. All tests were negative.

Complete Growth Medium BEGM from Lonza/Clonetics Corporation, Walkersville, MD 21793 (BEGM Bullet Kit; CC3170). The kit includes 500 mL basal medium and separate frozen additives from which we discard the gentamycin/ Amphotericin (GA) and Epinephrine and to which we add extra 5 ng/mL EGF, 70 ng/mL Phosphoethanolamine and 10% fetal bovine serum.
Subculturing

Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.

The flasks used should be precoated with a mixture of 0.01 mg/ml fibronectin, 0.03 mg/ml bovine collagen type I  and 0.01 mg/ml bovine serum albumin dissolved in BEBM medium. 

  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.05% (w/v) Trypsin-53mM EDTA solution (GIBCO cat# 25300-054) to remove all traces of serum which 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 with 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.
  4. Add 0.1% Soybean Trypsin inhibitor  and aspirate cells by gently pipetting. 
  5. To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes.
  6. Discard supernatant and resuspend cells in fresh growth medium.  Add appropriate aliquots of cell suspension to new coated culture vessels. 
  7. Place culture vessels in incubators at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended
Medium Renewal: Every 2 to 3 days

Flask Coating
 
  1. Prepare a mixture of 0.01 mg/mL fibronectin, 0.03 mg/mL bovine collagen type I and 0.01 mg/mL bovine serum albumin (BSA) dissolved in culture medium. Store pre-prepared Coating Solution at 4°C in cold room for up to 3 months. 
  2. For a growth area of 75 cm2, add 4.5 mL of the fibronectin/collagen/BSA solution and rock gently to coat the entire surface. 
  3. Incubate the freshly coated vessel(s) in a 37°C incubator overnight (it is preferable to use tissue culture vessels with tightened, plug-seal caps to prevent evaporation during the coating process).
  4. Store coated flasks with solution at room temperature, light protected, up to 1 month. Suction off solution before plating cells.
