scHeteroNet: A Heterophily‐Aware Graph Neural Network for Accurate Cell Type Annotation and Novel Cell Detection

Advanced Science, EarlyView.
scHeteroNet) is a novel graph neural network model that explicitly addresses heterophily in single‐cell sequencing data enabling accurate cell type annotation and novel cell type discovery. By leveraging heterophily‐aware message passing and novelty propagation mechanisms, scHeteroNet achieves superior performance in both cell annotation and detection ...

Dissecting the Spatial and Single‐Cell Transcriptomic Architecture of Cancer Stem Cell Niche Driving Tumor Progression in Gastric Cancer

Advanced Science, EarlyView.
A single‐cell and spatial transcriptional atlas reveals the architecture of human gastric cancer stem cell (CSC) niche and the developmental trajectory of CSCs. These CSCs interact with immunosuppressive immune cells thereby constructing immune‐suppressive niche, and inflammatory cancer‐associated fibroblast (iCAFs) to enhance stemness through ...

Extravasation of Borrelia burgdorferi Across the Blood–Brain Barrier is an Extremely Rare Event

Advanced Science, EarlyView.
Lyme disease is caused by vascular dissemination of the bacteria Borrelia. In a 3D tissue‐engineered microvessel model, Borrelia extravasation across the blood–brain barrier is extremely rare, implying that neuroborreliosis is not caused via direct cytotoxicity.

Vascular Endothelial Growth Factor

Ophthalmology, 2007
Vascular endothelial growth factor (VEGF) signalling is a key stimulant of tumour neovascular growth, survival and capillary permeability, which are critical to solid tumour progression. The intracellular signalling responses that induce an angiogenic phenotype are dependent upon VEGF binding to specific transmembrane receptors on the endothelium and ...

Intravitreal vascular endothelial growth factor [PDF]

Graefe's Archive for Clinical and Experimental Ophthalmology, 2014
To evaluate whether a specific pre-analytical stabilization regimen is needed for naïve vitreous taps to detect true values of intrinsic VEGF levels.Fourteen consecutive patients with different vitreomacular pathologies without blood-retina-barrier breakdown were scheduled for standard 23-gauge three-port pars plana vitrectomy, and naïve vitreous taps ...

Vascular endothelial growth factor.

Journal of neuro-oncology, 1997
Vascular endothelial growth factor (VEGF) is a hypoxia-inducible angiogenesis and vascular permeability factor which is expressed in high amounts in perinecrotic palisading cells in human glioblastomas. In vitro VEGF gene expression is enhanced approximately ten times by hypoxia.

Vascular Endothelial Growth Factor and Vascular Homeostasis

Proceedings of the American Thoracic Society, 2011
Vascular endothelial growth factor (VEGF) is the angiogenic factor promoting and orchestrating most, if not all, processes of neovascularization taking place in the embryo and the adult. VEGF is also required to sustain newly formed vessels and plays additional multiple roles in the maintenance and function of certain mature vascular beds ...

Vascular endothelial growth factor in the lung

American Journal of Physiology-Lung Cellular and Molecular Physiology, 2006
Vascular endothelial growth factor (VEGF) is a pluripotent growth and permeability factor that has a broad impact on endothelial cell function. The lung tissue is very rich in this protein; many different lung cells produce VEGF and also respond to VEGF.

Role of Vascular Endothelial Growth Factor and Vascular Endothelial Growth Factor Receptors in Vascular Development

1999
Distinct cellular processes mediate blood-vessel formation during embryogenesis (Beck and D’Amore 1997; Carmeliet and Collen 1998a; Folkman and D’Amore 1996; Noden 1989; Risau 1997; Wilting and Christ 1996) (Fig. 1). Initially, mesodermal cells differentiate in situ into early haemangioblasts and form cellular aggregates (blood islands), in which the ...
