Expression profile of CD54. The results of flow cytometry are shown. A: BM specimen from a patient without lymphoma; B: BM specimen from a DLBCL patient without BM involvement; C: BM specimen from a DLBCL patient with BM involvement. Purple cells: plasma cells; dark green cells: normal mature B cells (A and B) or lymphoma cells (C); light green: normal mature B cells (C). Normal mature B cells express a low level of CD54, while normal plasma cells express a high level of CD54. In Fig. C, lymphoma cells in dark green highly express CD54 compared to the residual normal mature B cells in light green color. These lymphoma cells have large FCS
