Aberrant expression of CBX7 in human follicular lymphomas. (A) Expression of CBX7, BCL-2, and BMI-1 in germinal center (GC, green) and follicular lymphoma (FL, red), as reported in ref. 18. (B) FL samples were stained by IHC by using anti-CBX7 antibodies and the CBX7 levels evaluated and quantified as explained in Materials and Methods. (C) Representative pictures of FL samples stained with CBX7 antibodies are shown. (D) CBX7 expression in secondary GC of the tonsil. Arrows indicate high CBX7 expression in germinal center histiocytes.
