Assisted computerized image analysis photomicrograph of cervical biopsies from patients 8 (A) and 9 (B) stained by immunohistochemistry for IL-2. IL-2-producing cells were identified by a juxtanuclear focal staining pattern (arrows) surrounded by extracellular immune reactivity caused by adherence of cytokines to matrix proteins. Tissue sections were counterstained with hematoxylin (blue). Magnification, ×400.
