| Research Abstract |
Using whole cell antigens prepared from the established lines of human malignant fibrous histiocytoma(MFH),we have generated four different monoclonal antibodies (FU3,FU4,FU5,FU6) by a mouse hybridoma technique.By indirect immunoperoxidase in frozen tissue sections,FU3 and FU4 revealed strong staining of perivascular mesenchymal cells and fibroblasts.Macrophages in granulation tissues as well as monocytes and other blood cells in normal peripheral blood were uniformly negative for the antigen detected by FU3.Immunoelectron microscopic studies demonstrated positive reactions with FU3 and FU4 on the surface of MFH cell membrane,suggesting that these antibodies recognized cell surface antigens.MFH shares antigenicity with perivascular mesenchymal cell and fibroblast.MFH may have a common origin from the perivascular mesenchymal cells that are supposed to have a potential for multidirectional differentiation.
