Are "A549" lung cancer cells a particular type or sub-type of lung cancer, or is this a generic code for lung cancer cells of all types?
Research cell line: A549 cells are human lung adenocarcinoma cells.The A549 cell line was developed in 1972 through the culturing of cancerous lung tissue. They are responsible for the diffusion of substances, such as water and electrolytes, across the alveoli of lungs. In addition these cells are able to synthesize lecithin and contain high level of unsaturated fatty acids. The A549 cell line is widely used as an in vitro model for drug metabolism and as a transfection host. ...Read moreSee 2 more doctor answers
Not fully know: Not fully know, possibly genetics. Importantly, smoking is the primary risk factor for causing 90% of lung cancer. Though it is clear that some people who smoke their whole lives never develop lung cancer, quitting smoking remains the most important aspect of lung cancer prevention and should be strongly encouraged. ...Read more

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
