Angio- and lymphangiogenesis are inherently related processes. However, how blood and lymphatic vessels regulate each other is unknown. This work introduces a novel mechanism explaining the temporal and spatial relation of blood and lymphatic vessels. Vascular endothelial growth factor-A (VEGF-A) surprisingly reduced VEGF-C in the supernatant of blood vessel endothelial cells, suggesting growth...

OBJECTIVE Vascular endothelial growth factor (VEGF) plays critical roles in the regulation of angiogenesis and lymphangiogenesis. However, tissue edema, hemorrhage, and inflammation occur when VEGF-A is used for angiogenic therapy. To design a novel angiogenic factor without severe side effects, we examined the biological function of chimeric VEGF-E(NZ7)/placental growth factor (PlGF), which is...

The vascular system is the first functional organ that starts to develop in the embryo. The extraembryonic mesodermal cells, so-called hemangioblasts, aggregate in the yolk sac to form blood islands, where they differentiate into an external endothelial cell (EC) layer and an inner core of blood cells. The external ECs subsequently constitute the primary capillary plexus. Shortly thereafter, th...

PURPOSE Vascular endothelial growth factor (VEGF) is a potent regulator of angiogenesis, which exerts direct effects on vascular endothelial cells, including endothelial cell proliferation and survival, tubulogenesis, and vascular permeability. In this study, we examined whether Neovastat, a naturally occurring multifunctional antiangiogenic drug, could inhibit the endothelial cell response to ...

Reduced tissue oxygen tension (hypoxia) is appreciated as an efficient stimulus for neovascularization. The effect of hypoxia on the very first stages of vascular development is, however, less well characterized. Here we show that hypoxic conditions (1% O2) potently stimulated formation of an extensive vascular network during a discrete stage of mouse embryonal stem cell differentiation. The mo...

Interactions between cancer cells and their microenvironment are critical for the development and progression of solid tumors. This study is the first to examine the role of all members of the ErbB tyrosine kinase receptors (epidermal growth factor receptor [EGFR], ErbB-2, ErbB-3, or ErbB-4), expressed singly or as paired receptor combinations, in the regulation of angiogenesis both in vitro an...

Abstract Cutaneous leishmaniasis (CL) is the spectrum of diseases caused by Leishmaniaparasites endemic to tropical and subtropical regions world causing 1–2 million new cases each year. Based on species infecting parasite host immune status, CL can be self-healing or lead permanent disfiguration. We showed a critical role for lymphatics in wound healing during L. majorinfection C57BL/6 mice, m...
