The chemokine CXCL12 significantly stimulated migration of Huh-7 (Fluorescence: 30880±3298 IE vs 15705±1801 IE; P=0.001), but not of Hep3B (Fluorescence: 14367±2694 IE vs 15885±1559 IE; NS) or HepG2 (Fluorescence: 7608±110 IE vs 7956±416 IE; NS) hepatoma cells (Figure 2B). The gene discussed is CXCL12; the disease is hepatocellular carcinoma.
