Lung cancer. Immunofluorescent Light Micrograph of carcinoma cancer cells of the lung. Carcinoma is the cancer that arises in epithelium, cells which line internal organs. Normal lung fibroblast cells are green. Smaller carcinoma cells (red) are seen growing upon this fibroblast lung tissue. Both cell types have blue nuclei. Lung cancer typically arises in the epithelium layer and is a common form of cancer, associated with cigarette smoking. Immunofluorescence is a staining technique which uses antibodies to attach fluorescent dyes to specific tissues and to molecules within the cell. Magnification: x125 at 35mm, x240 at 6x4.5cm size.
