| Organism | Homo sapiens, human |
| Tissue | stromal; liver |
| Cell Type | immortalized with SV40 large T antigen |
| Product Format | frozen |
| Morphology | fibroblast |
| Culture Properties | adherent |
| Biosafety Level | 2 Cells contain SV-40 viral DNA sequences
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Age | fetus |
| Applications | The cells produce flk-1 and some flk-2 ligands. The cell line was derived from human fetal liver tissue, and immortalized by transformation with an ecotropic retrovirus containing a temperature sensitive SV40 T-antigen (tsA58) and a G418 resistance gene. |
| Storage Conditions | liquid nitrogen vapor phase |
| Disclosure | This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC. |

| Derivation | The cell line was derived from human fetal liver tissue, and immortalized by transformation with an ecotropic retrovirus containing a temperature sensitive SV40 T-antigen (tsA58) and a G418 resistance gene. After several days at 37C, the temperature of the medium was lowered to 32C. Cells were selected with G418. The selected cells were expanded and maintained. The cells produce flk-1 and some flk-2 ligands. |
