A549 Cells

A549 cells are a type of human lung cancer cell widely used in scientific research. They originate from a tumor in the lungs of a 58-year-old male patient with alveolar (air-sac) carcinoma. Researchers use these cells to study lung cancer behavior, test new drugs, and understand lung diseases. They are grown in laboratory dishes under controlled conditions, allowing scientists to observe how lung cancer cells grow, respond to treatments, and interact with other cells, helping advance medical knowledge and potential therapies for lung-related illnesses.
