TNFRSF8 and neoplasm: The immunophenotype of the cells in culture (from hereon named “LM1 cells”) was confirmed to be the same as the primary tumor: The cells expressed CD138, VS38c, CD38 and EMA, showed fine granular cytoplasmic ALK-staining and expression of the immunoglobulin kappa light chain as well as gamma heavy chain (Figure 1) Like the primary tumors, LM1 cells were negative for CD30, T cell markers, CD20 and CD79a (Figure 1 and not shown).
