Abstract
Cartilage-derived morphogenic protein (CDMP)-1 and -2 belong to the bone morphogenetic protein (BMP) family in the transforming growth factor (TGF)-β superfamily. CDMP-1 and CDMP-2 were reported to play essential roles in limb cartilage and limb-joint formation in developing mice. Although pleomorphic adenoma of the salivary glands is an epithelial tumor, it frequently shows ectopic cartilaginous formation. These findings suggested that CDMP-1 and -2 may play essential roles in chondroid formation in salivary pleomorphic adenoma. To evaluate this hypothesis, we examined the expression and localization of CDMP-1 and -2 immunohistochemially in 20 normal human salivary glands and 35 pleomorphic adenomas. CDMP-1 was immunolocalized in the striated ducts and the intercalated ducts in the normal salivary glands. CDMP-1 was immunolocalized in the cuboidal neoplastic myoepithelial cells around the chondroid areas of the pleomorphic adenomas, whereas these molecules were not localized in the spindle-shaped neoplastic myoepithelial cells of the myxoid element or the lacuna cells of the chondroid element in these tumors. CDMP-2 was expressed neither in normal salivary glands nor any of the elements of the pleomorphic adenomas. Type-II collagen and aggrecan were immunolocalized throughout the matrix around the lacuna cells of the chondroid element, whereas type-X collagen was not immunlocalized in any epithelial or stromal elements, including the chondroid elements. Aggrecan was deposited not only on the chondroid matrix, but also on the myxoid stroma and intercellular spaces of the tubulo-glandular structures, whereas chondromodulin-I was deposited on the chondroid matrix. These results indicated that the cuboidal neoplastic myoepithelial cells around the chondroid areas expressed CDMP-1 and suggested that this molecule may play a role in the differentiation of neoplastic myoepithelial cells in pleomorphic adenoma. The phenotype of the lacuna cells was similar to that of mature to upper hypertrophic chondrocytes of the authentic cartilage. In conclusion, pleomorphic adenoma expressed CDMP-1 but not CDMP-2.
