| Derivation | 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]. |
| Antigen Expression | Antigen expression: Positive for fibroblast surface protein; Homo sapiens, expressed (fibroblast surface protein (FSP) was assayed by flow cytometry.). Negative for the pan-cytokeratin epithelial marker; Homo sapiens (cytokeratins were assayed by immunocytochemistry using a pan-cytokeratin antibody). |
| 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 |
| Subculturing | Volumes are given for a 75 cm2 flask. Recommended use of Corning® T-75 flasks (catalog #430641). Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
Subcultivation Ratio: 1:2 to 1:3 twice weekly
Medium Renewal: every 2 to 3 days
Note: Subculture when cell concentration reaches between 8 X 103 and 1 X 104 cells/cm2.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 13 in Culture Of Animal Cells: A Manual of Basic Technique by R. Ian Freshney, 5th edition, published by Wiley-Liss, N.Y., 2005. |
| Cryopreservation | Freeze medium: culture medium, 30%; fetal bovine serum, 60%; DMSO, 10% Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions | Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37°C |
| STR Profile | Amelogenin: X,Y CSF1PO: 10,12 D13S317: 8,9 D16S539: 9,13 D5S818: 12 D7S820: 11,12 THO1: 7,8 TPOX: 10,11 vWA: 16,18 |
| Population Doubling Level (PDL) | 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. |
