Isolation: Isolation date: 2001

Applications: CuFi-4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-4, was derived from lung of a 33-year-old patient with cystic fibrosis by dual retroviral infection with HPV-16E6/E7-LXSN and pBabe-hygro-hTERT. Consequently, the cells do not undergo growth arrest in cell culture due to exogenous expression of the telomerase and E6/E7 genes.

This cell line may be a useful model for studying ion channel physiology, therapeutic interventions for cystic fibrosis and innate immunity.

CuFi-4 cells are heterozygous for the cystic fibrosis-causing mutations delta F508/G551D. When seeded on semi-permeable filters and cultured at an air-liquid interface, they are capable of forming polarized, differentiated epithelia that exhibit transepithelial resistance and maintain the ion channel physiology expected of a bronchial epithelium.

Other hTERT-immortalized cell lines derived from cystic fibrosis HAE are also available from ATCC as ATCC CRL-4013 (CuFi-1), ATCC CRL-4016 (CuFi-5) and ATCC CRL-4017 (CuFi-6).

Cytogenetic Analysis: CuFi-4細胞The karyotypes of several different passages were determined. This is a human cell line of female origin, and the ploidies range from near-diploid to near-tetraploid. The karyology seems to stabilize at higher passages in the hyperdiploid range with trisomies or tetrasomies of chromosomes 1, 5, 8, 11 and 20. Additional copies of chromosomes 5 and 20 were the most consistent aberrations found throughout all the passages and ploidies.

Propagation: CuFi-4細胞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: 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 4 x 104 and 5 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: CuFi-4細胞about 34 hours
