Physiological MRI of microvascular architecture, neovascularization activity, and oxygen metabolism facilitate early recurrence detection in patients with IDH-mutant WHO grade 3 glioma [PDF]
Neuroradiology, 2021 Abstract Purpose This study aimed to determine the diagnostic performance of physiological MRI biomarkers including microvascular perfusion and architecture, neovascularization activity, tissue oxygen metabolism, and tension for recurrence detection of IDH-mutant WHO grade 3 glioma.

Proangiogenic cells enhanced persistent and physiologic neovascularization compared with macrophages [PDF]
Experimental & Molecular Medicine, 2015 Proangiogenic cells (PACs) display surface markers and secrete angiogenic factors similar to those used by myelomonocytic cells, but, unlike myelomonocytic cells, PACs enhance neovascularization activity in experimental ischemic diseases. This study was performed to reveal the differential neovascularization activities of PACs compared with those of ...

VEGF164-mediated Inflammation Is Required for Pathological, but Not Physiological, Ischemia-induced Retinal Neovascularization [PDF]
The Journal of Experimental Medicine, 2003 Hypoxia-induced VEGF governs both physiological retinal vascular development and pathological retinal neovascularization. In the current paper, the mechanisms of physiological and pathological neovascularization are compared and contrasted. During pathological neovascularization, both the absolute and relative expression levels for VEGF164 increased to

Bone Marrow Origin of Endothelial Progenitor Cells Responsible for Postnatal Vasculogenesis in Physiological and Pathological Neovascularization [PDF]
Circulation Research, 1999 Abstract —Circulating endothelial progenitor cells (EPCs) have been isolated in peripheral blood of adult species. To determine the origin and role of EPCs contributing to postnatal vasculogenesis, transgenic mice constitutively expressing β-galactosidase under the transcriptional regulation of an endothelial cell–specific ...

Inhibition of Tumor Necrosis Factor-α Improves Physiological Angiogenesis and Reduces Pathological Neovascularization in Ischemic Retinopathy [PDF]
The American Journal of Pathology, 2005 The present study was undertaken to test whether inhibition of the proangiogenic inflammatory cytokine tumor necrosis factor (TNF)-alpha can modulate retinal hypoxia and preretinal neovascularization in a murine model of oxygen-induced retinopathy (OIR).

Synchrotron Radiation Coronary Microangiography for Morphometric and Physiological Evaluation of Myocardial Neovascularization Induced by Endothelial Progenitor Cell Transplantation [PDF]
Arteriosclerosis, Thrombosis, and Vascular Biology, 2007 Background— Therapeutic effect of stem cell transplantation (SCTx) for myocardial neovascularization has been evaluated by histological capillary density in small animals. However, it has been technically difficult to obtain imaging evidence of collateral formation by conventional angiography.

Investigative Opthalmology & Visual Science, 2007 Recently, it was revealed that the inhibition of nonproteolytic activation of prorenin led to significant suppression of ocular inflammation in endotoxin-induced uveitis. The purpose of the present study was to investigate whether nonproteolytically activated prorenin plays a role in ischemia-induced retinal neovascularization.C57BL/6 neonatal mice ...

Investigative Opthalmology & Visual Science, 2006 Tumor necrosis factor (TNF)-alpha is one of the major cytokines in inflammation and apoptosis. It has been demonstrated that inhibition of TNFalpha can reduce leukocyte adhesion, vascular leakage, and apoptotic endothelial cell death in diabetes. This study was conducted to investigate the effect of TNF-Rp55 and TNF-Rp75 on retinal development in ...

The Matricellular Protein Cysteine-rich Protein 61 (CCN1/Cyr61) Enhances Physiological Adaptation of Retinal Vessels and Reduces Pathological Neovascularization Associated with Ischemic Retinopathy [PDF]
Journal of Biological Chemistry, 2011 Retinal vascular damages are the cardinal hallmarks of retinopathy of prematurity (ROP), a leading cause of vision impairment and blindness in childhood. Both angiogenesis and vasculogenesis are disrupted in the hyperoxia-induced vaso-obliteration phase, and recapitulated, although aberrantly, in the subsequent ischemia-induced neovessel formation ...

miR‐30a‐5p inhibition promotes interaction of Fas+endothelial cells and FasL+microglia to decrease pathological neovascularization and promote physiological angiogenesis [PDF]
Glia, 2018 AbstractIschemia‐induced angiogenesis contributes to various neuronal and retinal diseases, and often results in neurodegeneration and visual impairment. Current treatments involve the use of anti‐VEGF agents but are not successful in all cases. In this study we determined that miR‐30a‐5p is another important mediator of retinal angiogenesis.
