Calu-6 Cells

The Calu-6 cell line is a human non-small cell lung carcinoma (NSCLC) cell line derived from the pleural effusion of a 61-year-old male patient. Established in 1975, this cell line has been a critical model in lung cancer research. Calu-6 cells exhibit a distinct epithelial morphology and have been used extensively to study the biology of lung cancer, including mechanisms of metastasis, drug resistance, and the tumor microenvironment. These cells are particularly noted for their ability to form tumors in xenograft models, which makes them highly valuable for in vivo studies of tumor growth and response to therapeutics. Calu-6 is characterized by a high level of KRAS mutation, common in NSCLC, and provides a relevant model for studying the role of this oncogene in lung cancer. The cell line also displays several cytogenetic anomalies typical of cancer cells, such as complex karyotypes and aneuploidy, which contribute to its use in genetic studies. Research utilizing the Calu-6 cell line has helped in understanding the cellular mechanisms of lung cancer and in the development of therapeutic strategies. Its robust growth in culture and the ability to mimic clinical aspects of lung cancer make it an indispensable resource in oncological research.
