Abstract: | The ontogeny of circulating hemocytes and tumor cells in mollusks has been approached using monoclonal antibodies to normal cells. A monoclonal antibody, previously shown to identify an adhesion related protein (p130), has been used to define the reactivity of cells in tissues from normal soft-shell clams (Mya arenaria) and soft-shell clams with leukemia. Using immunoperoxidase technology, we have determined that hemocytes, connective tissue cells, and a subset of leukemia cells that are adherent share a cross-reactive epitope with cilia. |
