title: Immunohistochemical and immunochemical detection of a similar epitope in enamel proteins and monocyte-macrophage protein recognized by mouse monoclonal antibody MOMA-2.
abstract: These studies were made as a first step in elucidating unknown functions of enamel proteins in odontogenesis. The cytoplasm of ameloblasts and the proteins in dentine matrix before mineralization were stained with this monoclonal antibody. SDS-PAGE and Coomassie blue staining of proteins extracted from enamel showed several protein bands. Immunoblotting revealed that proteins recognized by this antibody were situated between 20-30 kDa. These results indicate that enamel proteins, presumably amelogenins, have an epitope resembling monocyte-macrophage protein. The findings suggest that epithelial-mesenchymal interaction in odontogenesis and preosteoblast-preosteoclast interaction in osteogenesis may be similar.
