Documentation

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

Cells contain Human papillomavirus (HPV) sequences

Cells contain SV40 sequences

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Detailed product information

General

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

Characteristics

Growth properties
Adherent
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. 
Age
33 years
Gender
Female
Immortalization method
HPV-16 E6/E7 and hTERT expression
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.
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. 

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete 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.
Temperature
37°C
Atmosphere
95% Air, 5% CO2
Handling procedure
To ensure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If storage of the frozen culture is necessary upon arrival, store the vial in liquid nitrogen vapor phase and NOT at –70°C. Storage at –70°C will result in loss of viability.
  1. Prepare a 25 cm2 or a 75 cm2 culture flask containing the recommended complete culture medium. Prior to the addition of the vial contents, the vessel containing the growth medium should be placed in the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6) and to avoid excessive alkalinity of the medium during recovery of the cells.
  2. Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water. Thawing should be rapid (approximately 2 minutes).
  3. Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All operations from this point on should be carried out under strict aseptic conditions.
  4. Transfer the vial contents to a centrifuge tube containing 9.0 mL of complete culture medium and centrifuge the cell suspension at approximately 125 x g for 5 to 7 minutes.
  5. Discard the supernatant and resuspend the cells in fresh growth medium (see the batch-specific information for the recommended dilution ratio). Add this suspension to the prepared culture vessel.
  6. Incubate the culture at 37°C in a suitable incubator.
  7. A 5% CO2/95% air atmosphere is recommended if using the medium described on this product sheet.
Subculturing procedure

 
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.

  1. Remove and discard culture medium.
  2. 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.
  3. 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.
  4. Transfer cell suspension to a centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes. Discard supernatant.
  5. 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.
  6. Incubate cultures at 37°C.
  7. 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
