Source Department of Stomatology, University of California, San Francisco, San Francisco, CA 94143, USA. Abstract OBJECTIVE: To describe the expression of integrins in the epithelium of oral hairy leukoplakia (HL) and compare to that of normal lateral tongue epithelium. MATERIALS AND METHODS: Immunohistochemistry to identify integrins (alpha 2, alpha 3, alpha 5, alpha 6, alpha v, beta 1) was performed, using a standard biotin-streptavidin-peroxidase technique on five clinically and histologically confirmed frozen biopsy specimens of HL and five normal lateral tongue control tissues.
