Conversely , classic HD ( CHD ) is heterogeneous because the tumor cells of a fraction of CHD display the BCL-6 ( - ) / syn-1 ( + ) phenotype of post-GC B-cells , whereas another fraction of CHD is constituted by a mixture of tumor cells reflecting the GC ( BCL-6 ( + ) / syn-1 ( - ) ) or post-GC ( BCL-6 ( - ) / syn-1 ( + ) ) phenotypes .
