Descripción

Origen línea celular

Human bronchial epithelium, normal

Descripción línea celular

BEAS-2B cells were derived from normal bronchial epithelium obtained from autopsy of non-cancerous individuals. Cells were infected with a replication-defective SV40/adenovirus 12 hybrid and cloned. Squamous differentiation can be observed in response to serum. This ability can be used for screening chemical and biological agents inducing or affecting differentiation and/or carcinogenesis. The cell line has been applied for studies of pneumococcal infection mechanisms. BEAS-2B was described to express keratins and SV40 T antigen. Subculturing the cells before confluency is necessary as confluent cultures rapidly undergo squamous terminal differentiation.

Aplicación

BEAS-2B Cell line has been used to study differentiation of squamous cells and effect of biological and chemical agents on differentiation.

Medio de cultivo

BEGM, also known as LHC-9 with modification (available from Clonetics Corporation, CC3171 (BEBM) plus additives CC4175 or BEGM Bullet Kit, CC3170); Note: Additives supplied contain gentamycin which has been omitted for culture at ECACC; media is serum-free.

Rutina de subcultivo

Passage sub-confluent cultures using 0.25% trypsin or trypsin/EDTA. Incubate at room temperature for 5-10 min until cells detach. Add fresh medium and disperse cells, centrifuge and resuspend pellet in medium. Seed into new flasks at 1500 to 3000 cells per cm². Flasks have to be precoated with a mixture of 0.01 mg/ml fibronectin, 0.03 mg/ml collagen and 0.001 mg/ml bovine serum albumin dissolved in BEGM. Add mixture at ratio of 0.2 ml per cm² surface area. Incubate at 5% CO₂, 37°C for at least 6 hours at 37oC. Remove excess fluid and allow flasks to dry by incubating at 37oC overnight, leaving the caps loose. Prior to addition of cells wash flask three times with PBS. Note: BEGM medium is almost serum-free, therefore trypsin inhibitor is essential. Add an equal or greater volume of trypsin inhibitor as trypsin used before, centrifuge and reseed cells in collagen coated flasks using culture medium.
