| 商品货号： | TS211301 |
| Organism： | Homo sapiens, human |
| Tissue： | lung; derived from metastatic site: bone marrow |
| Product Format： | frozen |
| Morphology： | epithelial |
| Culture Properties： | aggregates in suspension |
| Biosafety Level： | 1
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. |
| Disease： | carcinoma; small cell lung cancer (SCLC) |
| Gender： | male |
| Ethnicity： | Caucasian |
| Storage Conditions： | liquid nitrogen vapor phase |
| Karyotype： | This is a hyperdiploid human cell line., The modal chromosome number is 49, occurring at 28% with a frequency of higher ploidies of 1.3%. Ten to eleven markers were common to all cells including: der(1)t(1;3)(p22;p21), del(6)(q21), t(8q18q), del(12)(q13), der(14)t(14;?)(q32;?)., All had a single copy per cell. About 6 other markers were found, but they occurred only once in all metaphases karyotyped. Neither HSR nor DM were detected., Structurally normal B group chromosomes were not detected. All C group chromosomes were paired. A single copy of both the X and Y was found in all cells. |
| Derivation： | The NCI-H209 cell line was derived by A.F. Gazdar and associates in 1979 from the bone marrow of a patient with small cell cancer of the lung. |
| Clinical Data： | The bone marrow specimen was taken prior to therapy. |
| Oncogene： | pRB + (abnormal, RB1) |
| Tumorigenic： | Yes |
| Effects： | Yes, forms transplantable tumors with typical SCLC histology in nude mice |
| Comments： | C-myc DNA sequences are not amplified.
No gross structural DNA abnormalities were detected.
This is a cell line that grows as large aggregates in suspension. Only the aggregates are viable, but no meaningful viability percentage can be measured. The medium will normally contain large amounts of cell debris.
The cells express an aberrant form of RB1 that is not phosphorylated, apparently due to a single point mutation at codon 706 (Cys -> Phe).
The line is a classic SCLC cell line which expresses elevated levels of four biochemical markers (neuron specific enolase, brain isoenzyme of creatine kinase, L-DOPA decarboxylase and bombesin-like immunoreactivity.
The line produces normal amounts of p53 mRNA relative to normal lung.
