Calu-1 Cells

The Calu-1 cell line originates from human lung carcinoma, specifically non-small cell lung cancer (NSCLC). It was established from the pleural effusion of a 47-year-old Caucasian male with epidermoid carcinoma of the lung. This cell line exhibits epithelial-like morphology and has been used extensively in research focused on lung cancer biology, drug screening, and cytotoxicity studies. Calu-1 cells express several markers characteristic of lung epithelial cells and have been a valuable model for studying the molecular pathways involved in lung carcinogenesis and therapy resistance. Calu-1 cells are known for their high proliferation rate and robustness in culture, making them suitable for in vitro experimental setups. They retain several chromosomal abnormalities typical of cancer cells, which includes multiple copies of chromosomes 7 and 20, demonstrating their utility in genetic and cytogenetic studies. The cell line also exhibits mutations in key oncogenes and tumor suppressor genes like KRAS and TP53, respectively, which are of particular interest in lung cancer research. These genetic characteristics make Calu-1 a useful tool for investigating the impact of genetic alterations on cancer progression and for testing the efficacy of targeted therapies in a controlled environment.
