Integrins in Human Corneal Epithelium
Cornea, 1991Monoclonal antibodies (Mabs) were used for immunohistochemical location of integrin beta- (beta 1,3, and 4) and alpha subunits (alpha 1-6 and alpha v) in the epithelium of both normal and tissue-cultured human cornea. Immunoreaction for the beta 1 integrin subunit was the most intense at the membranes of the basal epithelial cells and weaker at the ...

Microcystic Dystrophy of Corneal Epithelium
Archives of Ophthalmology, 1966A new disease of the corneal epithelium called microcystic dystrophy was recently described by Cogan et al. 1 Clinically, this typically exhibits bilateral groups of grayishwhite round or comma-shaped deposits in the corneal epithelium. The disease appears to be more common in women than in men, and has been observed to cause a slight reduction of ...

Corneal epithelium following intraepikeratophakia
Journal of Cataract and Refractive Surgery, 1991The corneal epithelium in eight patients was surveyed by biomicroscopy and specular microscopy before and after the intraepikeratophakia procedure. Autografting of the epithelium was also examined by electron microscopy. Although the superficial layer of the epithelium was damaged, the wing cell layer remained intact, contributing to the ...

Fc receptors in corneal epithelium
Current Eye Research, 1989The corneal epithelia of the mouse, rabbit and human were shown to contain Fc receptors by an indirect method with immunoglobulins, labelled second antibody and the avidin-biotin peroxidase complex (ABC); and a direct method with the peroxidase conjugated Fc fragment.

Growth Factors and Corneal Epithelium
Cornea, 1988Regeneration of corneal epithelium following injury is essential for visual rehabilitation. A limited number of approaches are available for treating patients who fail to heal epithelial injuries adequately. The presence of specific receptors for epidermal growth factor (EGF) on epithelial cells suggests that this potent mitogen may play a role in ...

The fine structure of the corneal epithelium
Experimental Eye Research, 1962The fine structure of the corneal epithelium has been investigated with particular reference to the intercellular attachment areas or desmosomes. It has been found that the desmosomes vary markedly in structure; those on the basement membrane being different from those between the wing cells, and those between the wing cells again showing differences ...

Acetylcholine Synthesis in Corneal Epithelium
Archives of Ophthalmology, 1957It was shown by von Brucke in 1938 1 that corneal epithelium contains a remarkably high concentration of acetylcholine (ACh) and that corneal stroma contains almost none. The concentration in the corneal epithelium of rabbits appeared to be in the order of magnitude of 100γ to 200γ/gram and that in the stroma, of about 0.6γ/gram.

Replacement of Corneal Epithelium
Acta Ophthalmologica, 2011AbstractPurpose Ocular surface reconstruction with cultivated oral mucosal epithelial transplantation technique has potential in the treatment of patients with severe ocular surface injuries. Currently, this technique is mainly based on utilization of xenogenic/allogenic components such as murine feeders, serum and amniotic membrane.

The Effect of Corneal Epithelium on Corneal Curvature in Patients with Keratoconus
Seminars in Ophthalmology, 2014To investigate the effects of corneal epithelium on corneal curvature in patients with keratoconus.This is a prospective, nonrandomized study.Fifty-nine eyes of 47 patients diagnosed as keratoconus and for whom corneal collagen crosslinking (CXL) was recruited in this study.This study is a single-center clinical trial.

The intracellular potential of the corneal epithelium
Experimental Eye Research, 1964A microelectrode technique was used to investigate the potential difference across the epithelial cells of the cornea. This potential was found to be negative and increased as the microelectrode penetrated through the epithelium, the maximum value being obtained at an average depth of 53 μ ± 1 μ. On penetrating the stroma, the potential dropped sharply,
