Permits/Forms:In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimately responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.
Restrictions:This material requires that the Addendum for Commercial and For-Profit Organizations or the Addendum for Noncommercial and Academic Organizations be signed and returned to ATCC before shipment. The price listed above is for noncommercial and academic organizations only. Commercial and for-profit organizations should call for pricing.
Isolation: Isolation date: September 1995
Applications:In addition, it has been verified that no gross changes are observed in karyotype and morphology during the first 10 population doublings.
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.
The Barrett's esophagus cell line, CP-C (also identified as CP-94251) was derived from an endoscopic biopsy specimen obtained from a region of high-grade dysplasia.
Genetic instability studies using flow cytometry and FISH reveal the retention of elevated tetraploidy (G2/tetraploidy) in the hTERT-immortalized cells similar to the non-transduced parental cells.
Morphologically, the cell line is similar to early passage cultures exhibiting smaller cells with large nucleus to cytoplasm ratio.

Comments:The Barrett's esophagus cell line, CP-C (also identified as CP-94251) was derived from an endoscopic biopsy specimen obtained from a region of high-grade dysplasia. The cells were immortalized by transduction with a retroviral expression vector, pLXSN-hTERT, to create an immortalized cell line. [16173160 ]
Terminal restriction fragment lengths (TRF) analyses show the cells have increased telomerase activity and extended telomeres of about 12 kb. Morphologically, the cell line is similar to early passage cultures exhibiting smaller cells with large nucleus to cytoplasm ratio. Genetic instability studies using flow cytometry and FISH reveal the retention of elevated tetraploidy (G2/tetraploidy) in the hTERT-immortalized cells similar to the non-transduced parental cells.

This well-characterized pre-malignant culture represents a unique tool for studying esophageal cancer progression.

- 1 nM cholera toxin
- 20 mg/L adenine
- 140 ?g/ml BPE (Bovine Pituitary Extract)
- 0.1% ITS [Insulin-Transferrin-Sodium Selenite Supplement(Sigma, I1884)]

Subculturing: Protocol: 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 0.25% (w/v) Trypsin - 0.53 mM 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 37.0°C to facilitate dispersal. - Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
