Quantifying Lymphatic Vessel Density in Human Tissue Samples

2022
The development of new blood and lymphatic vessels, through the process of angiogenesis and lymphangiogenesis, respectively, is critical to the development and growth of tumors, and integral to the process of metastasis. Lymphatic vessel density can be assessed as a surrogate measure of lymphangiogenesis in human tissue samples.

Lymphatic vessel density is significantly increased in melanoma

Journal of Cutaneous Pathology, 2004
Background:  Melanoma is well known for its ability to involve regional lymph nodes in the early stage. However, the presence of lymphangiogenesis in melanoma is still controversial due to lack of lymphatic‐specific markers. The purpose of this study was to determine the intra‐ and peritumoral lymphatic vessel density (LVD) using a novel lymphatic ...

Retinal Vasculature Fractal Dimension Measures Vessel Density

Current Eye Research, 2015
The goal of this study was to provide the empirical evidence of fractal dimension as an indirect measure of retinal vasculature density.Two hundred retinal samples of right eye [57.0% females (n = 114) and 43.0% males (n = 86)] were selected from baseline visit. A custom-written software was used for vessel segmentation.

Chronic vessel ligation increases vessel wall strain and vessel length density in mesenteric microvascular networks

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
To study the role of hemodynamic stresses in microvascular network remodeling, a ligation strategy was developed to locally alter pressure and wall strain throughout the microvessel network of a single mesentery window. Additionally, a network model was developed to calculate the pre- and post-ligation pressures throughout the affected mesenteric ...

Vessel Density Mapping of Cerebral Small Vessels on 3D High Resolution Black Blood MRI

2023
Abstract Cerebral small vessels are largely inaccessible to existing clinical in vivo imaging technologies. This study aims to present a novel analysis pipeline for vessel density mapping of cerebral small vessels from high-resolution 3D black-blood MRI at 3T.

Vessel Density Ratio

Journal of Computer Assisted Tomography, 2006
We hypothesized that a "culprit" lesion in acute coronary syndrome (ACS) should have low overall vessel lumen and plaque density on multidetector computed tomography-assisted coronary angiography (MDCTA) because of lower calcification and the presence of occlusive thrombus.

A culture vessel for maintaining cells at high density

Journal of Tissue Culture Methods, 1994
The Sykes-Moore and Rose chambers have been used for many years in time lapse studies of subconfluent cell cultures. Unfortunately, use of a Sykes-Moore chamber for the time lapse studies of cells maintained at very high cell density was found to be unsatisfactory even if a medium perfusion system was employed.

Blood vessel density in canine osteosarcoma.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 1998
Canine osteosarcoma is a prevalent bone neoplasm which has similarities to the human disease. We used a retrospective study to investigate the possibility that tumor vascularity may provide useful prognostic information, indicative of the role of this parameter in progression of this cancer.

Lymphatic vessel density, microvessel density and lymphangiogenic growth factor expression in colorectal cancer

Colorectal Disease, 2007
AbstractObjective  Microvessel density (MVD) has been studied as a prognostic marker in human cancers. Quantification of lymphatic vessel density (LVD) is now possible by using new antibodies. Expression of the lymphangiogenic growth factors, VEGF‐C and VEGF‐D, is associated with poorer clinicopathological outcomes in various tumours.
