| Karyotype |
This is a near-diploid cell line of male origin. The most consistent karyotypic aberrations include trisomy of chromosome 5 and 20, monosomy of chromosome 15 or 16, and loss of the Y chromosome. Additionally, the polyploidy rate may increase slightly at high passage. |

| Derivation |
Human airway epithelial (HAE) cell line, CuFi-6, was derived from lung of a 20-year-old patient with cystic fibrosis by retroviral infection with HPV-16 E6/E7-LXSN. |
| Antigen Expression |
Positive for the epithelial marker pan-cytokeratin as assess by immunocytochemistry. |
| Comments |
CuFi-6 cells are homozygous for the delta F508 cystic fibrosis-causing mutation (delta F508/delta F508).
The cells do not undergo growth arrest in cell culture due to exogenous expression of the telomerase and E6/E7 genes.
Another hTERT-immortalized cell line derived from cystic fibrosis HAE is available as ATCC CRL-4013 (CuFi-1). |
| 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 μg/ml G-418.

| Subculturing |
Note: The culture flasks should be pre-coated with 60 µg/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 x g 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 5 x 103 to 1 x 104 viable cells/cm2 is recommended.
- Incubate cultures at 37°C.
- Subculture when cell concentration is between 2 x 104 and 3 x 104 cells/cm2.
Subcultivation ratio: A subcultivation ratio of 1:2 to 1:3 is recommended.
Medium renewal: every 3 to 4 days

| Population Doubling Level (PDL) |
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. We have also compared its karyotype, telomerase expression level, growth rate, morphology and tissue-specific markers when first recovered from cryopreservation with that of cells at 10+ population doublings to ensure that there is no change in these parameters and that the cells are capable of extended proliferation. |
