Comments: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. [RF84749]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. [RF84750]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. [RF84750]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. [RF84750]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. [RF84750]These immortalized human liver cells constitute an in vitro model for pharmacotoxicological studies and for the investigation of etiology and pathogenesis of human hepatocellular carcinoma.A culture submitted to the ATCC in May of 1989 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cycline. 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.The cured cell line is available as CRL-2706. The original patent deposit is available as CRL-10149
Propagation: ATCC complete growth medium: BEGM from 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.
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Growth Conditions: 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.
Subculturing: Protocol: Remove medium, add fresh 0.05% trypsin - 0.53 mM EDTA, rinse and remove trypsin. Allow the culture to sit at room temperature (or 37C) until the cells detach (about 5 . Neutralize the trypsin with 0.1% soybean trypsin inhibitor. Resuspend the cells in fresh medium, aspirate and dispense into coated flasks.
