Figure 2From: Chemokine CXCL12 activates dual CXCR4 and CXCR7-mediated signaling pathways in pancreatic cancer cellsCXCR4 and CXCR7 expression in pancreatic cancer cell lines. Immunoblotting was performed for CXCR4 and CXCR7 protein expression in established human pancreatic cancer cell lines. HT29 colon cancer cells were used as a negative control for CXCR7 expression. GAPDH was used as a loading control.Back to article page
