Isolation: Isolation date: 2000

Applications: NuLi-1細(xì)胞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.

DNA Profile (STR): Amelogenin: X,Y

Cytogenetic Analysis: This is a near-diploid human cell line of male origin with a polyploidy rate of 24%. There were copies of karyotypically normal X and Y-chromosomes present in most of the cells analyzed. Overall, some of the cells contained chromosomal abnormalities, with the most consistent being trisomy 5 and 20.

Age: 36

Gender: male

Comments: Human airway epithelial (HAE) cell line, NuLi-1, was derived from normal lung of a 36-year-old patient by dual retroviral infection with HPV-16E6/E7-LXSN [Pubmed: 1845902] and hTERT-LXSN [Pubmed: 9817205]. Consequently, the cells do not undergo growth arrest in cell culture due to exogenous expression of the telomerase and E6/E7 genes. NuLi-1 cells (wild type) do not express the delta F508 cystic fibrosis-causing mutation. Another hTERT-immortalized cell line, derived from HAE of a cystic fibrosis patient is also available as ATCC CRL-4013 (CuFi-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. These cell lines may be useful models for studying ion physiology, therapeutic interventions for cystic fibrosis and innate immunity [Pubmed: 12676769].

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.

Propagation: NuLi-1細(xì)胞ATCC 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 ?g/ml G-418.

Atmosphere: 5% CO2 in air recommended

Temperature: 37.0°C

Subculturing: Protocol:

Note: The culture flasks should be pre-coated with 60ug/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 sq.cm. 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 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.

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.

Transfer cell suspension to a centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes. Discard supernatant.

Resuspend the cell pellet in fresh growth medium. Add appropriate aliquots of the cell suspension to new culture vessels. An inoculum of 9 X 10(3) to 1.5 X 10(4) viable cells/sq. cm is recommended.

Incubate cultures at 37C.

Subculture when cell concentration is between 4 X 10(4) and 5 X 10(4) cells/sq. cm.

Subcultivation Ratio: 1:5

Medium Renewal: Every 2-3 days (do not wait longer)

Preservation: Freeze medium: BEGM with 30% FBS and 10% DMSO

Storage temperature: liquid nitrogen vapor phase

Doubling Time: about 43 hours
