Restrictions: This material requires that the Addendum for Commercial and For-Profit Organizations or the Addendum for Noncommercial and Academic Organizations be signed and returned to AT CC before shipment. The price listed above is for noncommercial and academic organizations only. Commerci al and for-profit organizations should call for pricing.

Isolation: Isolation date: 2001

Applications: CuFi-5細胞In addition, it has been verified that no gross changes are observed in karyotype and morphology during the first 10 population doublings.

As part of our quality control, we have tested this cell line for its ability to grow for a minimum of 15 population doublings after recovery from cryopreservation.

Human airway epithelial (HAE) cell line, CuFi-5, was derived from lung of a 32-year-old patient with cystic fibrosis by retroviral infection with hTERT and HPV-16E6/E7. Consequently, the cells do not undergo growth arrest in cell culture due to exogenous expression of the telomerase and E6/E7 genes.

Other hTERT-immortalized cell lines derived from cystic fibrosis HAE are also available from ATCC as ATCC CRL-4013 (CuFi-1), ATCC CRL-4015 (CuFi-4), and ATCC CRL-4017 (CuFi-6).

Cytogenetic Analysis: This is a near-diploid cell line of male origin in which the most consistent karyotypic aberrations are trisomy of chromosomes 5 and 20. Other non-clonal aberrations were found at early passage, but the karyology tended to stabilize within several passages.

Age: 32 years

CuFi-5 cells are homozygous for the delta F508 cystic fibrosis-causing mutation (delta F508/delta F508).

Other hTERT-immortalized cell lines derived from cystic fibrosis HAE are also available from ATCC as ATCC CRL-4013 (CuFi-1), ATCC CRL-4015 (CuFi-4), and ATCC CRL-4017 (CuFi-6).

Propagation: ATCC complete growth medium: These cells are grown in a serum-free medium: BEGM (Bronchial Epithelial Growth Medium, Serum-free) from Lonza (BEGM Bullet Kit; CC-3170) made of BEBM basal medium and SingleQuot additives (ATCC does not use gentamycin-amphotericin B) supplemented with 50 ?g/ml G-418.

Temperature: 37.0°C

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

Subculturing: Protocol:

Note: CuFi-5細胞The culture flasks should be pre-coated with 60μg/ml solution of Human Placental Collagen Type IV. (Sigma, Cat. No. C-7521) at least 18 hours in advance then air-dried and rinsed 2-3 times with Dulbecco's Phosphate Buffered Saline.

Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.

Remove and discard culture medium.

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: 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.

To remove Trypsin-EDTA solution, add 2.0 to 3.0 ml of 1% FBS in Dulbecco's Phosphate buffered Saline and aspirate cells by gently pipetting.

Transfer cell suspension to a centrifuge tube and spin at approximately 125 xg for 5 to 10 minutes. Discard supernatant.

Resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels. An inoculum of 1 x 104 to 2 x 104 viable cells/cm2 is recommended.

Incubate cultures at 37°C.

Subculture when cell concentration is between 3 x 104 and 4 x 104 cells/cm2.

Subcultivation ratio: A subcultivation ratio of 1:2 to 1:3 is recommended.

Medium renewal: every 2 to 3 days

Preservation: Freeze medium: BEGM with 30% FBS and 10% DMSO

Storage temperature: liquid nitrogen vapor phase

Doubling Time: approximately 36 hours
