Human Epithelial Related Antigen (hERA) in Salivary Glands and Their Tumors: Immunohistochemical Observations.

Interlobular excretory ducts of mammalian salivary glands: Structural and histochemical review

“…Variant isoforms of another transmembrane glycoprotein, CD44, have been identified in basal cells of EDs of human parotid glands (Terpe et al, 1994); no function for CD44 in salivary glands has been advanced. Human epithelial-related antigen (hERA), another transmembrane glycoprotein, has been identified in the columnar cells of the EDs of human parotid and submandibular glands, whereas it is basal cells in the sublingual and minor salivary mucous glands that are strongly labeled for this factor (Yamada et al, 1997). Human lung and gastric cancer antigen that closely resembles sialylated Lewis antigen has been localized in the basal cells of EDs of human submandibular (Tsuzi et al, 1989) and parotid glands (Shinohara et al, 1996).…”
