| Disease | Cystic fibrosis |
| Age | 33 years |
| Gender | Female |
| Applications | This cell line may be a useful model for studying ion channel physiology, therapeutic interventions for cystic fibrosis and innate immunity. |
| Storage Conditions | Liquid nitrogen vapor phase |
| Karyotype | 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. |

| Derivation | 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. |
| Antigen Expression | Antigen expression: This cell line is positive for epithelial marker pan-cytokeratin as assessed by immunocytochemistry. |
| Comments | 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. |
| 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 | Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Subcultivation ratio: A subcultivation ratio of 1:2 to 1:3 is recommended.
Medium renewal: every 2 to 3 days
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 13 in Culture Of Aminal Cells: A Manual of Basic Techniques by R. Ian Freshney, 5th edition, published by Wiley-Liss, N.Y., 2005. |
| Cryopreservation | Freeze medium: BEGM with 30% FBS and 10% DMSO Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions | Temperature: 37°C
Atmosphere: air, 95%; carbon dioxide (CO2), 5% |
| STR Profile | Amelogenin: X CSF1PO: 13 D13S317: 11,12 D16S539: 12,13 D5S818: 11,13 D7S820: 10,12 THO1: 7 TPOX: 8,11 vWA: 17,18 |
| 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. |
