Actin in Human Corneal Epithelium

Archives of Ophthalmology, 1985
Actin, a major protein involved in muscle cell contraction, is also associated with cell motility, cell-substrate adhesion, and cell-shape changes in non-muscle cells. By electrophoresis and scanning densitometry, actin was found to constitute about 4% to 6% of the total cellular protein in the human corneal epithelium.

Permeability of regenerated corneal epithelium

Experimental Eye Research, 1975
The penetration of non-metabolized 14carbon labelled α-amino-isobutyric acid (α-AIB), 3-o-methyl glucose, and d-mannitol across the regenerated corneal epithelium in rabbits has been determined in vivo and compared to penetration into bare stroma and across normal epithelium.

Image Analysis of the Corneal Epithelium

Ophthalmologica, 2010
The method for quantifying corneal epithelial images has been examined. When pictures were developed, the images were stored in the memory of the image processing system by video camera. The distribution of the density of the images was analyzed. The density of each pixel of an image was assigned one of 256 grades, from completely black to completely ...

Corneal Epithelium in Diabetic Patients

Cornea, 1991
The corneal epithelia of phakic control (n = 13), aphakic control (n = 10), diabetic phakic (n = 10), and diabetic aphakic patients (n = 13) were surveyed under a wide-field specular microscope with a special contact lens. In control patients, the corneal epithelium showed relatively hexagonal cells, which we divided into three groups: bright cells ...

Ultrastructure of conjunctival epithelium replacing corneal epithelium

Current Eye Research, 1986
After corneas of mice had been totally denuded of their epithelium by the application of n-heptanol, the new epithelium which grew over the corneas was studied by electron microscopy at intervals up to 7 months. The purpose was to compare the basal attachment of the new cells, derived from conjunctiva, with that of true corneal epithelial cells growing

Immunoelectrophoresis of the proteins of the corneal epithelium

Experimental Eye Research, 1963
The proteins of the corneal epithelium are separated into a greater number of fractions by high-tension agar electrophoresis than by paper electrophoresis. The distribution of the different fractions is greatly influenced by the ionic strength of the buffer solution.

ADHESIVE MECHANISMS OF THE CORNEAL EPITHELIUM

Acta Ophthalmologica, 1992
Abstract The corneal epithelium adheres to the stro‐ma through a series of linked structures termed collectively the adhesion complex. These structures include; intermediate filaments (keratin filaments) which are linked to the hemidesmosome; the hemidesmo‐some; the anchoring filaments which extend from the membrane at the hemidesmosome through the ...

Specular Microscopy of Corneal Epithelium

Archives of Ophthalmology, 1983
Specular microscopy was used to study the morphologic appearance of normal and regenerating rabbit corneal epithelium before and after corneal abrasion or heptanol application. Specular photomicrographs of the denuded area and healing epithelium were taken for two to three weeks as the epithelium regenerated, as well as prior to trauma.

Angiogenic activity of the corneal epithelium

Experimental Eye Research, 1985
A homogenate of corneal epithelial cells was tested to determine if it could induce vascularization in the cornea. Both fresh and cultured cells were used as sources of the homogenate which was evaluated in vivo using a self-contained system to perfuse it constantly into the corneal stroma.

Corneal Epithelium in Penetrating Keratoplasty

American Journal of Ophthalmology, 1980
We studied corneal epithelium in 66 patients with bullous keratopathy treated with penetrating keratoplasty using McCarey-Kaufman stored donor corneas. Epithelium was evaluated at times of storage, surgery, and postoperative dressing changes. Epithelium was intact in 43 of the donor corneas at storage, and 23 had 5 to 100% (median, 50%) epithelium ...
