In this study we examined the role for the chemokine CXCL12 and its receptors CXCR4/CXCR7 on schwann cells (SC) in the initiation of neural invasion in pancreatic cancer. SC exhibited hypoxia-induced CXCR4/CXCR7 expression in vitro and migrated toward CXCL12-expressing PCC. In PDAC patients, reduced CXCR4/CXCR7 expression in nerves correlated with increased pain. Therefore, PDAC-derived CXCL12 seems to induce tumor infiltration by SC during early carcinogenesis and to attenuate pain, possibly resulting in delayed diagnosis in PDAC.
