Fig. 1From: Difference in transducin-like enhancer of split 1 protein expression between basal cell adenomas and basal cell adenocarcinomas - an immunohistochemical studyNormal salivary glands (a: hematoxylin–eosin staining, b: immunostaining for TLE1). Normal salivary gland forms ducto-acinar units composed of acini, intercalated ducts, striated ducts, and excretory ducts (a). Acinic cells and intercalated ductal cells are positive, and myoepithelial cells and excretory ductal cells are negative for TLE1 (b)Back to article page
