Calu-3 Cells

Calu-3 cells are a human epithelial cell line derived from the lung adenocarcinoma of a 25-year-old in 1975. These cells exhibit epithelial morphology and are characterized by their ability to form tight junctions, desmosomes, and microvilli, mirroring the structural features of lung epithelium. Calu 3 cells are particularly noted for their high-level secretion of mucins, which are glycoproteins involved in protecting and lubricating the pulmonary airways, making them a relevant in vitro model for studying airway epithelial biology, including mucin production, secretion, and its regulation. Calu-3 human lung adenocarcinoma cells are used in drug discovery and development, particularly for assessing the absorption, distribution, metabolism, and excretion (ADME) of inhaled pharmaceuticals. Their ability to form a polarized monolayer when cultured on permeable supports makes them suitable for studying drug transport and the effects of drugs on the airway epithelium. Calu 3 cells, derived from human lung cancer cell types, are particularly relevant in the study of airway epithelial cells and their role in respiratory conditions. These cells originate from bronchial submucosal glands and are utilized in cell culture models to mimic the human airway, providing insights into respiratory function, epithelial cell injury, lung injury and the study of dieseases such as cystic fibrosis or SARS. The study of Calu 3 cells and their response to chemotherapeutic agents contributes to the broader field of lung cancer research, offering insights into the efficacy of treatments and the potential for developing more effective therapeutic strategies.
