| Disease： | Cystic fibrosis |
| Age： | 14 years |
| Gender： | Female |
| Applications： | These cell lines may be useful models for studying ion physiology, therapeutic interventions for cystic fibrosis and innate immunity Pubmed: 12676769. |
| Storage Conditions： | Liquid nitrogen vapor phase |
| Karyotype： | This is a near-diploid human cell line of female origin with a modal chromosome count of 46 and a polyploidy rate of 27%. There were two copies of a karyotypically normal X-chromosome present in most of the cells. Overall, some of the cells contained chromosomal abnormalities, with most consistent being trisomy 20. |

| Derivation： | Human airway epithelial (HAE) cell line, CuFi-1, was derived from lung of a 14-year-old patient with cystic fibrosis by dual retroviral infection with HPV-16E6/E7-LXSN Pubmed: 1845902 and hTERT-LXSN Pubmed: 9817205.xa0 |
| Comments： | The cells do not undergo growth arrest in cell culture due to exogenous expression of the telomerase and E6/E7 genes. CuFi-1 cells are homozygous for the delta F508 cystic fibrosis-causing mutation (delta F508/delta F508).xa0 Another hTERT-immortalized cell line, derived from normal HAE is also available as ATCC CRL-4011 (NuLi-1). Both cell lines, when seeded on semipermeable filters and grown at the air-liquid interface, are capable of forming polarized differentiated epithelia that exhibit transepithelial resistance and maintain the ion channel physiology expected of each genotype.xa0 |
| 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 Dulbeccox92s 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.
Subcultivation Ratio: 1:5
Medium Renewal: Every 2-3 days (do not exceed 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. |

| STR Profile： | Amelogenin: X CSF1PO: 12 D13S317: 11,13 D16S539: 11,14 D5S818: 12 D7S820: 8,11 THO1: 6,9.3 TPOX: 8,11 vWA: 17,20 |
| 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. |
