Control of vascular morphogenesis and homeostasis through the angiopoietin–Tie system
TLDR
The Tie receptors and their angiopoietin (Ang) ligands have been identified as the second vascular tissue-specific receptor Tyr kinase system and provide unique insights into the functions of this vascular signalling system.Abstract:
Angiogenesis, the growth of blood vessels, is a fundamental biological process that controls embryonic development and is also involved in numerous life-threatening human diseases. Much work in the field of angiogenesis research has centred on the vascular endothelial growth factor (VEGF)-VEGF receptor system. The Tie receptors and their angiopoietin (Ang) ligands have been identified as the second vascular tissue-specific receptor Tyr kinase system. Ang-Tie signalling is essential during embryonic vessel assembly and maturation, and functions as a key regulator of adult vascular homeostasis. The structural characteristics and the spatio-temporal regulation of the expression of receptors and ligands provide unique insights into the functions of this vascular signalling system.read more

TL;DR: It is shown that mice engineered to lack Angiopoietin-1 display angiogenic deficits reminiscent of those previously seen in mice lacking TIE2, demonstrating that AngiopOietIn-1 is a primary physiologic ligand for TIE1 and that it has critical in vivo angiogenesis actions that are distinct from VEGF and that are not reflected in the classic in vitro assays used to characterize VEGf.

Molecular regulation of vessel maturation.
TL;DR: The maturation of nascent vasculature, formed by vasculogenesis or angiogenesis, requires recruitment of mural cells, generation of an extracellular matrix and specialization of the vessel wall for structural support and regulation of vessel function.

Pituitary follicular cells secrete a novel heparin-binding growth factor specific for vascular endothelial cells
TL;DR: A growth factor for vascular endothelial cells identified in the media conditioned by bovine pituitary follicular cells and purified to homogeneity by a combination of ammonium sulfate precipitation, heparin-sepharose affinity chromatography and two reversed phase HPLC steps is proposed to be named VGF on the basis of its apparent target cell selectivity.
