Cell Type-Specific Expression of Angiopoietin-1 and Angiopoietin-2 Suggests a Role in Glioblastoma Angiogenesis

Angiopoietin-1 for Myocardial Angiogenesis

Cell type specific expression of vascular endothelial growth factor and angiopoietin-1 and -2 suggests an important role of astrocytes in cerebellar vascularization

The vascularization of the central nervous system occurs by angiogenic sprouting, a process in which different factors like vascular endothelial growth factor (VEGF) and angiopoietin (Ang)-1/2 must act in a coordinated fashion. We investigated how these factors participate in capillarization of the cerebellum, an area experiencing marked reorganization processes during its postnatal development...

Angiopoietin-1, angiopoietin-2 and Tie-2 expression in eutopic endometrium in advanced endometriosis.

Endometriosis is one of the most common gynaecological disorders, but its aetiology and pathogenesis remain obscure. The refluxed menstrual debris in women with endometriosis may be more prone to implantation, invasion and growth in the peritoneum or ovary through the actions of extracellular proteolysis and angiogenesis. It has been hypothesized that the endometrium from women with endometrios...

Plasma angiopoietin-1, angiopoietin-2, and angiopoietin receptor tie-2 levels in congestive heart failure.

OBJECTIVES The goal of this research was to test the hypothesis that plasma angiopoietin (Ang-1), its soluble receptor tie-2, and Ang-2 levels would be abnormal in patients with acute and chronic congestive heart failure (CHF) when compared with healthy controls. BACKGROUND Increased plasma vascular endothelial growth factor (VEGF) in CHF is suggestive of excess angiogenesis-possibly driven b...

Angiopoietin-1 induces sprouting angiogenesis in vitro

Sprouting of new capillaries from pre-existing blood vessels is a hallmark of angiogenesis during embryonic development and solid tumor growth [1]. In addition to the vascular endothelial growth factor (VEGF) and its receptors, the Tie receptors and their newly identified ligands, the angiopoietins, have been implicated in the control of blood vessel formation [2,3]. Although 'knockouts' of the...
