Figure 1From: Human telomerase RNA component (hTERC) gene amplification detected by FISH in precancerous lesions and carcinoma of the larynxA case of normal epithelium of the larynx. A. H&E stain. (magnification, ×200). B. Interphase FISH displaying a normal signal pattern containing two copies (arrow) each of hTERC (red) and chromosome 3 centromere specific probe CSP3 (the internal control probe) (green), the CSP3: hTERC signal pattern is 2:2 (green:red).
