Multiple myeloma (MM) plasma cells (PC) are CD38+. A ligand for CD38 is the adhesion molecule CD31. By flow cytometry and immunocytochemistry we have investigated whether malignant PC co-express CD38 and CD31. All 68 patients studied were CD38+. 14/14 monoclonal gammopathies of undetermined significance (MGUS) and 39/39 plasmacytic MM patients co-expressed CD38 and CD31 at high density. Only 1/11 plasmablastic MM and 1/4 plasma cell leukaemias (PCL) expressed CD31. These data indicated that PC malignancies co-expressed high levels of both CD38 and its ligand CD31, with the exception of plasmablastic MM and PCL.

Human myeloma cells express the CD38 ligand CD31.

Abstract

Multiple myeloma (MM) plasma cells (PC) are CD38+. A ligand for CD38 is the adhesion molecule CD31. By flow cytometry and immunocytochemistry we have investigated whether malignant PC co-express CD38 and CD31. All 68 patients studied were CD38+. 14/14 monoclonal gammopathies of undetermined significance (MGUS) and 39/39 plasmacytic MM patients co-expressed CD38 and CD31 at high density. Only 1/11 plasmablastic MM and 1/4 plasma cell leukaemias (PCL) expressed CD31. These data indicated that PC malignancies co-expressed high levels of both CD38 and its ligand CD31, with the exception of plasmablastic MM and PCL.
