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 immortalized by CDK4

Cells immortalized by hTERT

Cells contain SV40 promoter 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

The immortalized HSAEC1-KT cells show a stable epithelial morphology and differentiated cytokeratin isoforms after over 100 population doublings, express the stem cell marker p63 and high levels of p16INK4a, and have an intact p53 checkpoint pathway (RefRamirez RD, Sheridan S, Girard L, et al. Immortalization of human bronchial epithelial cells in the absence of viral oncoproteins. Cancer Res. 64(24):9027-9034, 2004. PubMed: 15604268).  

The HSAEC1-KT cells also exhibit characteristics of normal cells such as contact inhibition of growth and failure to form soft agar colonies or form tumors in immune compromised mice (RefKalita M, et al. Systems approaches to modeling chronic mucosal inflammation. Biomed. Res. Int. 2013: 505864, 2013. PubMed: 24228254).

TGFβ-treated HSAEC1-KT cells showed an elongated shape with markedly induced F-actin staining. This morphological change of enhanced front-rear polarity and cytoskeletal actin rearrangement are characteristic morphological changes of EMT (epithelial mesenchymal transition) (RefKalita M, et al. Systems approaches to modeling chronic mucosal inflammation. Biomed. Res. Int. 2013: 505864, 2013. PubMed: 24228254).

Adherent
Derivation

The HSAEC1-KT cell line was established by infecting primary human small airway epithelial cell culture with human telomerase (hTERT) and mouse cyclin dependent kinase 4 (CDK4) expressing retrovirus constructs and selecting under 250 ng/mL puromycin and 30 ug/mL G418 as described in PMID: 15604268 (RefRamirez RD, Sheridan S, Girard L, et al. Immortalization of human bronchial epithelial cells in the absence of viral oncoproteins. Cancer Res. 64(24):9027-9034, 2004. PubMed: 15604268)

Age

Gender
Male
Immortalization method
hTERT expression and mouse cyclin dependent kinase 4 (CDK4) expressing retrovirus
Karyotype

Cytogenetic analysis was performed on G-banded metaphase cells from the human cell line HSAEC1-KT. Several abnormal male near-diploid karyotypes are found: 

Clone 1 demonstrates trisomy 5 with no other aberrations. 47,XY,+5 

Clone 2 demonstrates trisomy 5 and 20 with no other aberrations. 48,XY,+5,+20 

Clone 3 demonstrates trisomy 5, an isochromosome of the long-arm of chromosome 10, resulting in three copies of the chromosome 10 long-arm and only one copy of the short-arm, and trisomy 20. 48,XY,+5,i(10)(p10),+20

Clone 4 demonstrates a deletion on the short-arm of chromosome 10 at band p10, a deletion on the short-arm of chromosome 17 at band p13, and trisomy 20. 47,XY,del(10)(p10),del(17)(p13),+20.

Antigen expression
Positive for p63 (TP63) and Clara cell 10 (CC10) protein

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
SAGM BulletKit medium (Lonza CC-3119 and CC-4124)

To make the complete culture medium, add SAGM™ SingleQuots™ (Lonza CC-4124) which contains supplements and growth factors (BPE, Hydrocortisone, hEGF, Epinephrine, Transferrin, Insulin, Retinoic Acid, Triiodothyronine, BSA-FAF) to 500 mL bottle of SABM Basal Medium™, phenol red free basal medium (Lonza CC-3119)

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 3.0 mL of complete culture medium, mix gently, then slowly add an additional 7 mL of complete growth medium and centrifuge the cell suspension at approximately 1000 rpm for 2 minutes at room temperature.
  5. Discard the supernatant and resuspend the cells in 3 mL of fresh growth medium. Count the cells and seed at recommended seeding density.  
  6. Incubate the culture at 37°C in a suitable incubator.
Subculturing procedure
Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation solutions for culture vessels of other sizes.

Subculture when the culture is about 90% confluent.
  1. Remove and discard spent medium.
  2. Briefly rinse the cells with Dulbecco's Phosphate Buffered Saline (DPBS, ATCC 30-2200), 1 mL / 25 cm2 and discard rinse solution.
  3. Add Trypsin-EDTA, at 1 mL / 25 cm2, for Primary Cells (ATCC PCS-999-003) to the flask. Incubate at 37°C for 4-6 min (until 90% of the cells have detached).
  4. Rapt flask gently to ensure cells are detached.  Add 2% FBS in DPBS at 1 mL / 25 cm2 to neutralize the trypsin.
  5. Centrifuge cells at 1000rpm for 5 min at room temperature.
  6. Remove supernatant. Resuspend pellet in 6.0 to 8.0 mL Complete Growth Medium.
  7. Count cells, and seed 8.0 x 103 to 10.0 x 103 viable cells/cm2 to new culture vessels.
Medium Renewal: Every 2-3 days.
Reagents for cryopreservation
Complete growth medium supplemented with 10% (v/v) FBS and 10% (v/v) DMSO (ATCC 4-X).
