Figure 3. Immunohistochemical expression of SFRP4 protein in cancer tissues and matched adjacent normal tissues from 200 patients with resectable PDAC showed cytoplasmic staining.

Figure 3

(A) SFRP4 was predominantly strongly positive in normal ductal epithelial cells. (B) Normal ductal epithelial cells were weakly positive for SFRP4 in only a small portion of patients. (C) SFRP4 was weakly positive in PDAC tissues in only a small portion of patients. (D) SFRP4 expression was predominantly absent in PDAC tissues.
