(C, D) Show that over 80% of plasma cells exhibiting moderate or strong immunostaining for Bcl-2 and survivin, respectively (200 x). (E) Shows that Bcl-2 is expressed in the cytoplasm and cell membrane of plasma cells (1000 x), and (F) shows that survivin is expressed in the cytoplasm and/or nucleus of plasma cells (1000 x).
