Tumorigenic:Yes
Age: 20 years
Gender: female
Ethnicity: Caucasian, White
Comments:NL20 (ATCC CRL-2503 ) is an immortalized, nontumorigenic human bronchial epithelial cell line derived from normal bronchus taken from an accident victim at autopsy. [47429 ]
The cell line was established by transfection with the origin of replication-defective SV40 large T plasmid, p129.
NL20 cells at passage 183 were inoculated into nude mice and a small slowly growing subcutaneous tumor developed from a minor clone in this otherwise stable cell line.
After three months the tumor was removed and placed in culture. At passage 3, these cells were re-injected into nude mice.
One of the resulting tumors was dissociated, placed in culture and designated NL20-TA. This cell line (ATCC CRL-2504 ) remains tumorigenic up to at least passage 250.
Neoplastic transformation of the NL20 cell line was associated with loss of chromosome 18 together with acquisition of multiple copies of 9q21.2-->34. [47431 ]
The non-tumorigenic NL20 cell line and the tumorigenic NL20-TA cell line form a pair of immortal cell lines that can be used to study tumor progression.
Propagation: ATCC complete growth medium: Ham's F12 medium with 1.5 g/L sodium bicarbonate, 2.7 g/L glucose, 2.0 mM L-glutamine, 0.1 mM nonessential amino acids, 0.005 mg/ml insulin, 10 ng/ml epidermal growth factor, 0.001 mg/ml transferrin, 500 ng/ml hydrocortisone and 4% fetal bovine serum
Temperature: 37.0°C
Subculturing: Subcultivation Ratio: A subcultivation ratio of 1:50 to 1:500 is recommended
Medium Renewal: Every 2 to 3 days
Remove medium, add dissociation solution (0.02% EDTA and 5% dialized fetal bovine serum in Ca-Mg free Hanks' BSS) and allow the flask to sit at 37C for 12 minutes or until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Subculture weekly.
Preservation: culture medium 95%; DMSO, 5%
Related Products:recommended serum:ATCC 30-2020
parental cell line:ATCC CRL-2503
