Neoangiogenesis is an important pathophysiological feature of liver scarring, but a functional role of angiostatic CXCR3 chemokines in this process is unclear. We therefore investigated neoangiogenesis in carbon tetrachloride (CCl4)-induced liver fibrosis in<\/jats:bold>\n                      <jats:bold>Cxcr3<\/jats:bold>\n                      <jats:bold>\u2212\/\u2212 and wildtype mice by histological, molecular, and functional imaging methods. Furthermore, we assessed the direct role of vascular endothelial growth factor (VEGF) overexpression on liver angiogenesis and the fibroproliferative response using a Tet-inducible bitransgenic mouse model. The feasibility of attenuation of angiogenesis and associated liver fibrosis by therapeutic treatment with the angiostatic chemokine Cxcl9 was systematically analyzed<\/jats:bold>\n                      <jats:bold>in vitro<\/jats:bold>\n                      <jats:bold>and<\/jats:bold>\n                      <jats:bold>in vivo<\/jats:bold>\n                      <jats:bold>.

Systemic VEGF overexpression led to a fibrogenic response within the liver and was associated with a significantly increased Cxcl9 expression.<\/jats:bold>\n                      <jats:bold>In vitro<\/jats:bold>\n                      <jats:bold>, Cxcl9 displayed strong antiproliferative and antimigratory effects on VEGF-stimulated endothelial cells and stellate cells by way of reduced VEGFR2 (KDR), phospholipase C\u03b3 (PLC\u03b3), and extracellular signal-regulated kinase (ERK) phosphorylation, identifying this chemokine as a direct counter-regulatory molecule of VEGF signaling within the liver.
