Figure 1From: Tumor infiltrating B-cells are increased in prostate cancer tissue Immunohistochemical staining of prostatectomy sections with anti-CD20 antibody. Paraffin-embedded, formalin fixed prostatectomy sections were stained with anti-CD20 and counterstained with hematoxylin, The majority of CD20 immunostained B-cells are localized in immune cell foci. Many in close proximity to prostate cancer cells as shown. Inset shows whole slide scan with blue-pen marked tumor regions in each prostatectomy section.Back to article page
