Applications: BJ-5ta細(xì)胞TAs 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 firstrecovered 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.

The hTERT-immortalized foreskin fibroblast cell line, BJ-5ta, was derived by transfecting the BJ foreskin fibroblast cell line with the pGRN145 hTERT-expressing plasmid (ATCC MBA-141) at population doubling 58. Cells were cultured in medium containing hygromycin B until stable clones were selected [Pubmed: 9454332].

Propagation: ATCC complete growth medium: A 4:1 mixture of Dulbecco's medium and Medium 199 with supplements as follows :

4 parts of Dulbecco's Modified Eagle's Medium containing 4 mM L-glutamine, 4.5 g/L glucose and 1.5 g/L sodium bicarbonate

1 part of Medium 199

Supplemented with:

0.01 mg/ml hygromycin B

10% fetal bovine serum

Atmosphere: air, 95%; BJ-5ta細(xì)胞carbon dioxide (CO2), 5%

Temperature: 37.0°C

Growth Conditions: Subculture when cell concentration reaches between 8 X 10(3) and 1 X 10(4) cells/cm2.

Subculturing: Protocol: Volumes are given for a 75-cm2 flask; proportionally reduce or increase the amount of dissociation medium for culture vessels of other sizes.

Remove and discard culture medium.

Add 3.0 to 5.0 ml of 0.25% trypsin, 0.53 mM EDTA solution to the flask and observe cells under an inverted microscope until the cell layer is dispersed (usually within 5 to 15 minutes).Note: To avoid clumping do not hit or shake the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37C to facilitate dispersal.

Add 6.0 to 10.0 ml of complete growth medium and aspirate cells by gently pipetting.

Add appropriate aliquots of the cell suspension to new culture vessels.

An inoculum of 3 x 10(3) to 5 x 10(3) viable cells/cm2 is recommended.

Subcultivation Ratio: 1:2 to 1:3 twice weekly

Medium Renewal: every 2 to 3 days

Preservation: Freeze medium: culture medium, 30%; fetal bovine serum, 60%; DMSO, 10%

Storage temperature: liquid nitrogen vapor phase

Doubling Time: 62 hr
