Comments: HBE135-E6E7細(xì)胞The HBE135-E6E7 cell line was derived from normal bronchial epithelium taken from a man undergoing lobectomy for squamous cell carcinoma [PubMed: 8601403]. Cells from the primary explant in their first passage were infected with the recombinant retrovirus LXSN16E6E7 containing the human papilloma virus (HPV) E6E7 gene. Cells were selected in the presence of 0.4 mg/ml G418 [PubMed: 8601403]. Northern blot hybridization shows that immortalized HBE cells express high levels of mRNA for epidermal growth factor receptor (EGFR), transforming growth factor-alpha (TGF-alpha), and amphiregulin (AR), but not epidermal growth factor (EGF) [PubMed: 8601403]. This cell line may be used as a reference in cDNA microarray studies to demonstrate lung cancer profiles correlating with clinical outcome or biology of tumors [PubMed: 12036904].

Propagation: ATCC complete growth medium: Keratinocyte-Serum Free medium with 5 ng/ml human recombinant EGF (do not filter) and 0.05 mg/ml bovine pituitary extract (Invitrogen, formerly GIBCO-BRL, Cat. No. 17005-042) and supplemented with 0.005 mg/ml insulin and 500 ng/ml hydrocortisone.

Atmosphere: air, 95%; carbon dioxide (CO2), 5%

Temperature: 37.0°C

Subculturing: Protocol:

Remove and discard culture medium.

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.

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: HBE135-E6E7細(xì)胞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.

Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.

To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximately 125 xg for 5 to 10 minutes.Discard supernatant and resuspend cells in fresh growth medium. Add appropriate aliquots of cell suspension to new culture vessels.

Incubate cultures at 37?C.

Subcultivation Ratio: 1:3 to 1:4

Medium Renewal: Every 2 to 3 days

Preservation: Freeze medium: Complete growth medium supplemented with 10% (v/v) DMSO

Storage temperature: liquid nitrogen vapor phase

Doubling Time: 24 to 30
