Tumor angiogenesis is enforced by autocrine regulation of high-mobility group box 1

The endothelium plays a pivotal role in the progression of solid tumors and is considered a highly relevant target for therapy. However, it emerges that current clinical angiogenesis inhibitors that act through inhibition of tumor-derived growth factors ar ...

Proteolytic Processing Regulates Placental Growth Factor Activities

Jeffrey Alan Hubbell, Stéphanie Elisabeth Metzger, Martin Ehrbar, Manuel Koch

Placental growth factor (PlGF) is a critical mediator of blood vessel formation, yet mechanisms of its action and regulation are incompletely understood. Here we demonstrate that proteolytic processing regulates the biological activity of PlGF. Specificall ...

Interfering with UDP-GlcNAc Metabolism and Heparan Sulfate Expression Using a Sugar Analogue Reduces Angiogenesis

Patrycja Nowak-Sliwinska

Heparan sulfate (HS), a long linear polysaccharide, is implicated in various steps of tumorigenesis, including angiogenesis. We successfully interfered with HS biosynthesis using a peracetylated 4-deoxy analogue of the HS constituent GlcNAc and studied the ...

Disruption of notch1 induces vascular remodeling, intussusceptive angiogenesis, and angiosarcomas in livers of mice

Freddy Radtke

Notch signaling mediates embryonic vascular development and normal vascular remodeling; Notch1 knockout mice develop nodular regenerative hyperplasia (NRH). The pathogenesis of NRH is unclear, but has been associated with vascular injury in the liver sinus ...

Engineering the growth factor microenvironment with fibronectin domains to promote wound and bone tissue healing

Jeffrey Alan Hubbell, Mikaël Martino, Federico Tortelli, Mayumi Mochizuki Martino

Although growth factors naturally exert their morphogenetic influences within the context of the extracellular matrix microenvironment, the interactions among growth factors, their receptors, and other extracellular matrix components are typically ignored ...

Engineering of Signaling Microenvironments with Fibronectin Domains to Enhance Tissue Regeneration

Mikaël Martino

Conducting tissue healing and regeneration through biomaterials and morphogens is still an unrealized goal. Understand the multiple roles of the extracellular matrix (ECM) is indeed essential for the design of successful regenerative medicine strategies. D ...

Extracellular matrix in angiogenesis: dynamic structures with translational potential

Jeffrey Alan Hubbell

The vascular network is an integral component of most organs. Beyond assuring an adequate supply of oxygen and nutrients for normal tissue function, vascular structures provide also a critical interface in the balance of tissue homoeostasis and immune func ...

Biologicals and fetal cell therapy for wound healing and scar management

Dominique Pioletti, Corinne Scaletta, Nathalie Hirt-Burri, Lee Ann Laurent-Applegate

Few biopharmaceutical preparations developed from biologicals are available for tissue regeneration and scar management. When developing biological treatments with cellular therapy, selection of cell types and establishment of consistent cell banks are cru ...

Pericytes promote endothelial cell survival through induction of autocrine VEGF-A signaling and Bcl-w expression

Douglas Hanahan

Endothelial cells (ECs) in blood vessels under formation are stabilized by the recruitment of pericytes, both in normal tissues and during angiogenesis in pathologic situations, including neoplasia. In the tumor vasculature, besides supporting the function ...
