Characteristics of lymphoid neogenesis expressed in lymphoid aggregates found in a salpingitis sample. Paraffin sections of a diagnosed case of salpingitis with large lymphoid aggregates were stained with various antibodies to characterize attributes defining lymphoid neogenesis. Notice the distinct expression of (A) CXCL13 and (C) T-cell (CD3) and (D) B-cell (CD20) subsets found within a large lymphoid aggregate identified in human fallopian tube tissue with known salpingitis. Negative control (B). Representative images from five salpingitis and five tubal ligation cases. (original 200x magnification).
