Figure 5From: Expression of the costimulatory molecule B7-H3 is associated with prolonged survival in human pancreatic cancer Representative immunohistochemical stainings for B7-H3 (A, C) and CD8 (B, D) in pancreatic cancer tissues. (A) Pancreatic cancer tissue section with strong B7-H3 immunoreactivity. (B) Consecutive section with immunostaining for CD8 shows the infiltration of numerous CD8+ T cells (arrows). (C) Pancreatic cancer tissue section with weak tumor B7-H3 immunoreactivity. (D) Consecutive section with immunostaining for CD8 shows no CD8+ tumor-infiltrating T cells.Back to article page
