TNC and familial pancreatic carcinoma: For example, PDPN is also expressed in lymphatic endothelial cell.36, 37 NG2 and PDGFR‐β are commonly used to identify pericytes.38 In the stroma of pancreatic cancer, distinct populations of CAF differentially contribute to desmoplasia and inflammation and are molecularly distinguishable through α‐SMA expression and IL‐6 secretion.39 In this study, we found CAF derived from NPC represents the high expression of α‐SMA, FAP, PDGFR‐α/β, and TN‐C, consistent with other reports for the marker of CAF in other types of cancer.
