In arterial trees, D f a very sensitive indicator decreased from 1. Simon Barriga , Sheila C. Vascular Network-to-Tree Transitions in Developing Coronary Vessels Vascular trees, which are tapering, asymmetric structures characterized by bifurcational branching, often form from the progressive remodeling of relatively symmetric, homogeneous vascular networks. The basic three analytical options, their capabilities, and output are further described below. A novel assay of angiogenesis in the quail chorioallantoic membrane: Applications include progression of neovascular disease in clinical images of the human retina, effects of the stimulator vascular endothelial growth factor VEGF and inhibitor triamcinolone acetonide TA on vascular or lymphatic trees and networks in the developing mouse retina and quail chorioallantoic membrane CAM , and vascular network-to-tree transitions for developing coronary vessels.

To accomplish the vessel segmentation i. Applications include progression of vascular disease in the human retina from ophthalmic clinical images; effects of angiogenic and lymphangiogenic regulators in the avian CAM and developing murine retina, and development of murine and avian embryonic coronary vessels. The Image Processing Handbook.

McKay and Dan J. Mature vascular trees typically develop from immature, capillary-like vasculogenic networks.

Predictive factors for short-term visual outcome after intravitreal triamcinolone acetonide injection for diabetic macular oedema: Disease Progression in Vascular Trees of Human Retina Major sources of blindness in diabetic retinopathy and other retinal vascular diseases are macular ischemia and retinal neovascularization, which impairs retinal function and can obscure retinal vision through hemorrhage and eventually traction retinal detachment.

Generational analysis reveals that TGF-beta1 inhibits the rate of angiogenesis in vivo by selective decrease in the number of new vessels. Parameters are reported in pixel units and optionally in physical units if a microscope calibration factor is provided by the user.

Within each angiogram, the arterial and venous trees were extracted as overlapping binary vascular patterns by semi-automatic computer processing Avakian et al.

As visualized by confocal microscopy at relatively low magnification, large numbers of isolated vascular progenitor cells appear as punctate staining and are being recruited to growing lymphatics Parsons-Wingerter et al.

Compared to PBS-treated control A—Cvessel density and diameter decreased considerably in the peripheral vasculogenic capillary networks of the developing mouse retina D—F following treatment with TA prior to P Averaging of many parameters of a vascular tree such as vessel diameter or vessel length is not a highly meaningful analysis when these parameters vary so greatly throughout a branching vascular tree.

Output data include images processed into various vascular maps for example, see Fig. Fibroblast growth factor-2 selectively stimulates angiogenesis of small vessels in arterial tree. Furthermore, VEGF greatly disrupted normal lymphatic architecture, which by E8 is organized as small lymphatic vessels loosely surrounding the smaller blood vessels and vesegn as large lymphatic networks tightly enclosing larger blood vessels Fig.

At P15, for example, the mouse retina displays peripheral vasculogenic capillary networks that will quickly remodel into mature vascular trees Benjamin et al. For example, quantifying an average vessel diameter over many branching generations is not a particularly useful result. Decreases in venous density gesgen less marked. Software output includes colorized image maps with quantification fesgen local vessel diameter, fractal dimension, tortuosity and avascular spacing.

Quantification of microvascular remodeling as a meaningful discovery tool requires mapping and measurement of site-specific changes within vascular trees and networks. Vascular networks are relatively symmetric, homogeneous, non-branching structures characterized by enclosed avascular spaces i.

Coronary vessels will eventually attach to the aorta at E Open in a separate window. Transportation Transforming the Grid: Angioarchitectural heterogeneity in human glioblastoma multiforme: All results of this methodological analysis would require confirmation by much larger research and clinical studies.

Nerve growth factor NGF promotes angiogenesis in the quail chorioallantoic membrane. VESGEN 2D Software Description VESGEN 2D is an automated microvascular mapping and quantification software that provides an interactive, flexible, menu-driven user interface UI to accommodate the evolving needs of researchers grappling with the complexities of in vivo vascular morphological analysis for angiogenesis and lymphangiogenesis applications.

VESGEN was used to map and quantify progression of human diabetic retinopathy DRa vascular disease that is the major cause of blindness in working-aged adults. Vascular Networks in the Mouse Retina Vascular networks were identified by fluorescence microscopy for retinal flat mounts obtained from mice at postnatal day 15 P15when the retina and its blood vessels are still developing.
