| Disease： | squamous cell carcinoma |
| Gender： | male |
| Applications： | This cell line is a suitable transfection host. |
| Storage Conditions： | liquid nitrogen vapor temperature |
| Karyotype： | This is a hypotriploid human cell line. The modal chromosome number is 58 occurring at 30%. The frequency of higher ploidies was 3.2%. Over 30 marker chromosomes were common to all cells, and four others were found in some cells. Among the common markers were 1q+, t(1q8q), 2q+, der(16)t(3;16)(q21;q22), der(19)t(13;19)(q21;q13), and der(5)t(5;5)(p15pq13). Generally, there were two copies of der(5) in each cell. Normal Y and D group chromosomes were absent, and the X chromosome was single. |
| Derivation： | The NCI-H520 cell line was derived by A.F. Gazdar and associates in 1982 from a sample of a lung mass taken from a patient with squamous cell carcimoma of the lung. |
| Clinical Data： | male |
| Tumorigenic： | Yes |
| Effects： | Yes, in nude mice inoculated subcutaneously with 10(7) cells (Tumors developed within 21 days at 100% frequency (5/5).) |
| Comments： | The cells express greatly reduced levels of p53 mRNA relative to normal lung tissue, but exhibit no gross structural DNA abnormalities. The cells stain positively for keratin and vimentin but are negative for neurofilament triplet protein. The line can be cloned in soft agar (with or without serum). |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
|
| Subculturing： | Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 mL of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37°C) until the cells detach. Add fresh culture medium, aspirate and dispense into new culture flasks.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended
Medium Renewal: 2 to 3 times per week |
| Cryopreservation： | Freeze medium: Complete growth medium, 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor temperature |
| Culture Conditions： | Temperature: 37°C |
