Permits and Restrictions	View Permits
Organism	Homo sapiens, human
Tissue	lung, bronchus
Cell Type	epithelial virus transformed
Product Format	frozen
Morphology	epithelial
Culture Properties	adherent
Biosafety Level	2 [Cells contain polyomavirus DNA sequences] Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Disease	normal
Applications	This cell line is a suitable transfection host. The cells retain the ability to undergo squamous differentiation in response to serum, and can be used to screen chemical and biological agents for ability to induce or affect differentiation and/or carcinogenesis.
Storage Conditions	liquid nitrogen vapor phase
Disclosure	This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC.

Images
Derivation	Epithelial cells were isolated from normal human bronchial epithelium obtained from autopsy of non-cancerous individuals. The cells were infected with an adenovirus 12-SV40 virus hybrid (Ad12SV40) and cloned.
Clinical Data	Epithelial cells were isolated from normal human bronchial epithelium obtained from autopsy of healthy individuals.
Tumorigenic	The cells were not tumorigenic in immunosuppressed mice, but did form colonies in semisolid medium.
Effects	Yes, the cells did form colonies in semisolid medium No, the cells were not tumorigenic in immunosuppressed mice
Comments	The cells stain positively for keratins and SV40 T antigen.

Complete Growth Medium	The base medium for this cell line (BEBM) along with all the additives can be obtained from Lonza/Clonetics Corporation as a kit: BEGM, Kit Catalog No. CC-3170. ATCC does not use the GA-1000 (gentamycin-amphotericin B mix) provided with the BEGM kit. Note: Do not filter complete medium.
Subculturing	These cells should be subcultured before reaching confluence since confluent cultures rapidly undergo squamous terminal differentiation. Volumes used in this protocol are for 75 cm² flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning^® T-75 flasks (catalog #430641) are recommended for subculturing this product. Remove and discard culture medium. Add 2.0 to 3.0 mL of 0.25% Trypsin - 0.53mM EDTA solution containing 0.5% polyvinylpyrrolidone (PVP) to flask and observe cells under an inverted microscope until cell layer is dispersed (usually with 5 to 10 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. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Transfer cell suspension to centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes Discard supernatant and resuspend cells in fresh growth medium. Inoculate new flasks at 1500 to 3000 cells per cm². The culture flasks used should be pre-coated with a mixture of 0.01mg/ml fibronectin, 0.03 mg/ml bovine collagen type I and 0.01 mg/mL bovine serum albumin dissolved in BEBM. Place culture flasks in incubators at 37°C. Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in *Culture of Animal Cells, a manual of Basic Technique* by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994. Interval: Subcultured before reaching confluence. Medium Renewal: Every 2 to 3 days Flask Coating 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. 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. 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). Store coated flasks with solution at room temperature, light protected, up to 1 month. Suction off solution before plating cells.
Cryopreservation	Freeze medium: Complete growth medium supplemented with 1% PVP and 7.5% DMSO Storage temperature: liquid nitrogen vapor phase
Culture Conditions	Atmosphere: air, 95%; carbon dioxide (CO₂), 5% Temperature: 37°C Growth Conditions: The culture flasks used should be pre-coated 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 (see references: U.S. Pat. 4,885,238 and Lechner, J.F. and LaVeck, M.A. A serum-free method for culturing normal bronchial epithelial cells at clonal density.
