Figure 2. Differential expression of B7-H4 in liver metastases and primary pancreatic tumors.
The immunohistochemical score of B7-H4 expression in the liver metastases was higher than in the matched primary pancreatic cancer in 15 paired cases (p < 0.05). And the immunohistochemical score of B7-H4 expression in the matched primary pancreatic cancer was higher than in the control group (p < 0.05).
