Gold nanoparticles as high-resolution X-ray imaging contrast agents for the analysis of tumor-related micro-vasculature

Background: Angiogenesis is widely investigated in conjunction with cancer development, in particular because of the possibility of early stage detection and of new therapeutic strategies. However, such studies are negatively affected by the limitations of ...

Role of Jagged1 in Arterial Lesions After Vascular Injury

Freddy Radtke, Qi Zhou, Hui Gong

Objective-Impaired regeneration of endothelial cells (EC) and overactivity of vascular smooth muscle cells (VSMC) are hallmarks of the arterial lesions associated with aging. The occurrence of 2 opposing cellular processes in the same arterial milieu makes ...

Organometallic Ruthenium(II) Arene Compounds with Antiangiogenic Activity

Paul Joseph Dyson, Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Angela Casini, Alexey Nazarov

The antimetastatic ruthenium (II) compounds [Ru(eta(6)-p-cymene)Cl-2(PTA)] (PTA = 1,3,5-triaza-7-phosphaadamantane) (RAPTA-C) and [Ru(eta(6)-toluene)Cl-2(PTA)] (RAPTA-T), as well as their analogues [Ru(eta(6)-p-cymene)Cl-2(DAPTA)] (DAPTA = (3,7-diacetyl-1, ...

Leukocyte-endothelial cell interaction is necessary for photodynamic therapy induced vascular permeabilization

Hubert van den Bergh, Elodie Debefve, Hans-Anton Lehr

Photodynamic therapy (PDT) affects vascular barrier function and thus increases vessel permeability. This phenomenon may be exploited to facilitate targeted drug delivery and may lead to a new clinical application of photodynamic therapy. Here, we investig ...

Targeting the ANG2/TIE2 axis inhibits tumor growth and metastasis by impairing angiogenesis and disabling rebounds of proangiogenic myeloid cells

Michele De Palma, Ferdinando Pucci

Tumor-infiltrating myeloid cells convey proangiogenic programs that counteract the efficacy of antiangiogenic therapy. Here, we show that blocking angiopoietin-2 (ANG2), a TIE2 ligand and angiogenic factor expressed by activated endothelial cells (ECs), re ...

In vitro lymphatic endothelial morphogenesis

Carolyn Yong Pullin

Cell organization into functional multicellular three-dimensional structures is a long-standing challenge. In particular, engineering of vascularized tissues requires both blood and lymphatic neovascular network formation in a simultaneous and coordinated ...

Angiopoietin 2 stimulates TIE2-expressing monocytes to suppress T cell activation and to promote regulatory T cell expansion

Michele De Palma

Angiopoietin 2 (ANGPT2) is a proangiogenic cytokine whose expression is often upregulated by endothelial cells in tumors. Expression of its receptor, TIE2, defines a highly proangiogenic subpopulation of myeloid cells in circulation and tumors called TIE2- ...

Identification and functional response of interstitial Cajal-like cells from rat mesenteric artery

Jean-Jacques Meister, Jean-Louis Bény, Lara Buscemi Estefanell, Aurélie Formey de Saint Louvent

Cells with irregular shapes, numerous long thin filaments, and morphological similarities to the gastrointestinal interstitial cells of Cajal (ICCs) have been observed in the wall of some blood vessels. These ICC-like cells (ICC-LCs) do not correspond to t ...

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 ...

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 ...
