Comparison of Endothelial Cell Density in Diabetics and a Control Population
American Journal of Ophthalmology, 1980We compared the endothelial cell density of 96 corneas from 52 diabetics with proliferative diabetic retinopathy with 61 corneas from 32 normal subjects by specular microscopy. Although the regression curve of the diabetic group was steeper, we found no statistically significant difference in endothelial cell density between the two groups.

Endothelial cells injured by oxidized low density lipoprotein
American Journal of Hematology, 1995AbstractCultured endothelial cells from bovine aorta were exposed to oxidized low density lipoprotein and examined by electron microscopy. The endothelial cells contracted slightly and the intercellular junctions became unclear. Some osmiophilic material increased in the cytoplasm.

A fluorometric assay for the measurement of endothelial cell density in vitro
In Vitro Cellular & Developmental Biology - Animal, 1998A fluorometric assay for determining endothelial cell numbers based on the endogenous enzyme acid phosphatase is described. In preliminary studies, three substrates--p-nitrophenyl phosphate, 4-methylumbelliferyl phosphate, and 2'-[2-benzthiazoyl]-6'-hydroxy-benthiazole phosphate (AttoPhos)--were compared with respect to their kinetic, optimum assay ...

Endothelial Cell Perturbation and Low‐Density Lipoprotein
Annals of the New York Academy of Sciences, 1987The focal entry and accumulation of LDL within the arterial wall of the normal animal may represent an early stage in the development of the atherosclerotic plaque. Concentrations of LDL 10 to 100 times normal medial concentrations might be difficult to clear from the arterial wall, permitting accumulation of lipid.

Reliability of Corneal Thickness and Endothelial Cell Density Measures
Journal of Refractive Surgery, 2003ABSTRACT PURPOSE: We evaluated the reliability and agreement between the Orbscan, an ultrasonic pachymeter (Humphrey 855), and the Konan SP 9000-LC in terms of central corneal thickness. The Konan was also used to study the reliability and agreement between endothelial cell density measures. METHODS: Twenty-five normal subjects were

Corneal endothelial cell density and the integrity of the monolayer are essential for maintenance of a clear cornea. In 1992, Williams et al. introduced a method to estimate the endothelial cell density in histopathologic examination. It would enable an evaluation of the corneal host endothelium, even if preoperative measurement was not possible.

Endothelialization has been considered a promising method to improve the biocompatibility of vascular implanted biomaterials. However, little is known about the anti-coagulation, anti-inflammatory, anti-atherosclerosis and anti-shedding property of the attached endothelial cells (ECs) and the relationship with their bio-environment and material ...

To investigate the effect of the surface gradient density of growth factor on the migration of endothelial cells (ECs), an approach to fabricate a gradient density of vascular endothelial growth factor (VEGF) onto silicon slides has been developed in this study.

High-density lipoprotein and cerebral endothelial cells in vitro: Interactions and transport
Biochemical Pharmacology, 1995Primary cultures of bovine cerebral endothelial cells were used as an in vitro model for the blood-brain barrier to study the transport and interactions of high-density lipoprotein (HDL) across monolayers of these cells. Transport of 125I-apoE free HDL across a monolayer of bovine cerebral endothelial cells occurred in a linear fashion up to a ...
