Establishment and characterization of human non-small cell lung cancer cell lines.

Non-small cell lung cancer (NSCLC), a highly malignant tumor, is common in China and is associated with a very poor 5-year survival rate. To better understand the cancer biology of this disease, we report here the establishment of three new NSCLC cell lines, SCC210011, SCC211441 and ACC212102, from the tumor tissue of three NSCLC patients. By histological analysis, we found that all three cell lines displayed the typical features of endothelial cancer cells. The population doubling times of SCC210011, SCC211441 and ACC212102 cells were 42, 38 and 25 h, respectively. Our cytogenetic studies indicated that these cell lines exhibit structural and numerical chromosomal abnormalities. Furthermore, the tumorigenicity in nude mice was confirmed, and H&E staining results revealed that they resembled the primary tissue. These newly established cell lines may serve as useful models for studying the molecular pathogenesis of NSCLC.
