limiting membrane

Astrocytes form an outer limiting membrane to interact with the pia.

Within the brain, the glial limiting membrane is an important constituent of the blood-brain barrier.

Monkeys and other primates have been found to have a glial limiting membrane extremely similar to humans.

Rarely diagnosed, it is a very early cancer that has not spread below the limiting membrane of the first layer of anal tissue.

The inner limiting membrane is the boundary between the retina and the vitreous body, formed by astrocytes and the end feet of Müller cells.

For instance, in E. multilocularis, the cysts have an ultra thin limiting membrane and the germinal epithelium may bud externally.

Back-fusion is the fusion of internal (intraluminal) vesicles within multivesicular bodies or late endosomes with the endosome's limiting membrane.

The disk can be covered with a thin diffusion limiting membrane (e.g. low-density polyethylene, polyethersulphone) depending on the application the device is being used for.

In cestodes the tegument is further covered with highly specialized microvilli, called "microtriches", projecting from the outer limiting membrane of the tegument.

The external limiting membrane (or outer limiting membrane) is one of the ten distinct layers of the retina of the eye.

Syneresis: there is collapse of the vitreous due to collection of synchytic fluid between the posterior hyaloid membrane and the internal limiting membrane of the retina.

The glia limitans, or the glial limiting membrane, is a thin barrier of astrocyte foot processes associated with the parenchymal basal lamina surrounding the brain and spinal cord.

Small breaks in the internal limiting membrane (ILM) after PVD also may provide retinal astrocytes access to the vitreous cavity, where they may subsequently proliferate.

Macular pucker, epimacular membrane, preretinal membrane, cellophane maculopathy, retina wrinkle, surface wrinkling retinopathy, premacular fibrosis, and internal limiting membrane disease.

Descemet's membrane (also posterior limiting membrane): a thin acellular layer that serves as the modified basement membrane of the corneal endothelium, from which the cells are derived.

Because the glia limitans serves such an important structural and physiological function in human beings, it is unsurprising that evolutionary precursors of the glial limiting membrane can be found in many other animals.

The two different classifications of glial limiting membrane, the glia limitans perivascularis and the glia limitans superficialis, have nearly identical structures, however, they can be distinguished from each other by their location within the brain.

In early development of the retina, the medullary epithelial cells acquire polarity, such that a basement membrane associated with the vitreous forms the internal limiting membrane on one side, while terminal bars form the outer limiting membrane on the other side.

The reason that different routes of administration lead to different cell types being transfected (e.g., different tropism) is that the inner limiting membrane (ILM) and the various retinal layers act as physical barriers for the delivery of drugs and vectors to the deeper retinal layers.

Bowman's layer (also known as the anterior limiting membrane, when in fact it is not a membrane but a condensed layer of collagen): a tough layer that protects the corneal stroma, consisting of a similar irregularly arranged collagen fibers, mainly type I collagen fibrils, essentially a type of stroma.
