TL;DR: Gold nanoparticles can interact selectively with heparin-binding glycoproteins and inhibit their activity resulting in inhibition of endothelial/fibroblast cell proliferation in vitro and VEGF-induced permeability as well as angiogenesis in vivo.
Abstract: Here, we report an intrinsic property of gold nanoparticles (nanogold): they can interact selectively with heparin-binding glycoproteins and inhibit their activity. Gold nanoparticles specifically bound vascular permeability factor/vascular endothelial growth factor (VPF/VEGF)-165 and basic fibroblast growth factor, two endothelial cell mitogens and mediators of angiogenesis resulting in inhibition of endothelial/fibroblast cell proliferation in vitro and VEGF-induced permeability as well as angiogenesis in vivo. In contrast, nanogold did not inhibit VEGF-121 or epidermal growth factor, two non-heparin-binding growth factors, mediated cell proliferation. Gold nanoparticles significantly inhibited VEGF receptor-2 phosphorylation, intracellular calcium release, and migration and RhoA activation in vitro. These results report for the first time a novel property of gold nanoparticles to bind heparin-binding proteins and thereby inhibit their subsequent signaling events.

TL;DR: A central role for RAGE is identified in disordered wound healing associated with diabetes, and it is suggested that blockade of this receptor might represent a targeted strategy to restore effective wound repair in this disorder.
Abstract: Receptor for advanced glycation end-products (RAGE), and two of its ligands, AGE and EN-RAGEs (members of the S100/calgranulin family of pro-inflammatory cytokines), display enhanced expression in slowly resolving full-thickness excisional wounds developed in genetically diabetic db+/db+ mice. We tested the concept that blockade of RAGE, using soluble(s) RAGE, the extracellular ligand-binding domain of the receptor, would enhance wound closure in these animals. Administration of sRAGE accelerated the development of appropriately limited inflammatory cell infiltration and activation in wound foci. In parallel with accelerated wound closure at later times, blockade of RAGE suppressed levels of cytokines; tumor necrosis factor-α; interleukin-6; and matrix metalloproteinases-2, -3, and -9. In addition, generation of thick, well-vascularized granulation tissue was enhanced, in parallel with increased levels of platelet-derived growth factor-B and vascular endothelial growth factor. These findings identify a central role for RAGE in disordered wound healing associated with diabetes, and suggest that blockade of this receptor might represent a targeted strategy to restore effective wound repair in this disorder.

TL;DR: It is demonstrated that some lineage-specific genes are only expressed during distinct developmental stages and new molecular markers for blood vascular and lymphatic endothelium are identified with important implications for future studies of vascular development and function.
Abstract: In mammals, the lymphatic vascular system develops by budding of lymphatic progenitor endothelial cells from embryonic veins to form a distinct network of draining vessels with important functions in the immune response and in cancer metastasis. However, the lineage-specific molecular characteristics of blood vascular versus lymphatic endothelium have remained poorly defined. We isolated lymphatic endothelial cells (LECs) and blood vascular endothelial cells (BVECs) by immunomagnetic isolation directly from human skin. Cultured LECs but not BVECs expressed the lymphatic markers Prox1 and LYVE-1 and formed LYVE-1-positive vascular tubes after implantation in vivo. Transcriptional profiling studies revealed increased expression of several extracellular matrix and adhesion molecules in BVECs, including versican, collagens, laminin, and N-cadherin, and of the growth factor receptors endoglin and vascular endothelial growth factor receptor-1/Flt-1. Differential immunostains of human skin confirmed the blood vessel-specific expression of these genes. During embryonic development, endoglin expression was gradually down-regulated on lymphatic endothelium whereas vascular endothelial growth factor receptor-1 was absent from lymphatics. We also identified several genes with specific expression in LECs. These results demonstrate that some lineage-specific genes are only expressed during distinct developmental stages and they identify new molecular markers for blood vascular and lymphatic endothelium with important implications for future studies of vascular development and function.
