Tissue Expression of Low and High Molecular Weight Cytokeratins in Lung Carcinoma Sections: Its Correlation with Some Clinic-Pathological Features

Figure 3

Conventional fluorescence microphotographs of non-small cell lung carcinomas. (a) Intense, (b) intense but focal, and (c) moderate and diffuse expression of high molecular weight cytokeratins (CKs 1, 5, 10, and 14) mainly located in the cytoplasm of malignant epithelial cells. FITC-labeled cytokeratin (green signal). Nuclei contrasted with propidium iodide (red signal). Yellow bars = 100 μm.
