Establishment and comparative characterization of novel squamous cell non-small cell lung cancer cell lines and their corresponding tumor tissue.

2010

Abstract Background Cell lines play an important role for studying tumor biology and novel therapeutic agents. Particularly in pulmonary squamous cell carcinoma (SCC) the availability of cell lines is limited and knowledge about their representativeness for corresponding tumor tissue is scanty. Materials and methods We established three novel SCC cell lines from fresh tumor tissue of 28 donors, including 8 SCC. Two cell lines were derived from different localizations of the same donor, i.e. primary tumor and lymph node metastasis. This represents a so far unique combination in lung cancer. The genotypes, gene expression profiles and mutational status of epidermal growth factor receptor ( EG…
