NCI-H441 Cells

The NCI-H441 cell line, also known as H441, established in 1982 from the pleural effusion of a male patient with papillary adenocarcinoma of the lung, is a well-characterized epithelial adenocarcinoma cell line. These cells are extensively utilized in biological research for their relevance to lung epithelial biology, making them a critical in vitro model for studies on transepithelial transport and the epithelial barrier function. The NCI-H441 cell line serves as a vital tool in advancing our understanding of pulmonary drug disposition and tumor kinetics. Its use in 3D cell culture models allows for the detailed study of how drugs are absorbed, distributed, metabolized, and excreted within the lung environment, closely mimicking in vivo conditions. Given their origin and characteristics, NCI-H441 cells are particularly valuable in research focused on the distal lung and related diseases, including lung adenocarcinoma, serving as a stable and relevant cell model for understanding the mechanisms of lung diseases and evaluating potential therapeutic interventions. NCI-H441 cells are instrumental in 3D cell culture, high-throughput screening, and toxicology studies, providing valuable data on cellular responses and the efficacy of therapeutic agents. A notable application of the human cell line H441 involves their use as a transfection host for expressing pulmonary surfactant protein (SP-B), utilizing the firefly luciferase reporter system, which emphasizes their role in inhalation biopharmaceutics and transepithelial transport studies. This capability, alongside their expression of mRNA and protein for major surfactant apoprotein (SP-A), highlights the cell line's significance in investigating lung function and disorders, especially those affecting surfactant regulation and synthesis.
