Müller cells in fish have the ability to revert back to a stem cell form and regenerate damaged eye tissue. Humans and mice also have Müller cells, but internal signals prevent the cell type from carrying out regenerative duties.

Muller cell expression of glial fibrillary acidic protein (GFAP) in WE-cell transplanted retinas of RCS dystrophic rats. Current Eye Research: Vol. 12, No. 9, pp. 841-849. The eye proteome Eyes are responsible for the detection of light and its subsequent conversion of visual stimuli to neuronal signals that are transported to the visual centers of the brain.

Müller cells, the major type of glial cells in the retina, are responsible for the homeostatic and metabolic support of retinal neurons. By mediating transcellular ion, water, and bicarbonate transport, Müller cells control the composition of the extracellular space fluid.

Patton and colleagues have discovered a mechanism by which decreased GABA levels are sensed by Müller glia to initiate a regenerative response. Several endogenous populations of cells localized to the eye have been shown to be capable of replacing some or all retinal cell types in various species; 1) an endogenous population of progenitor cells in the periphery of the eye referred to as the ciliary marginal zone (CMZ), 2) the retinal pigmented epithelium, 3) non-pigmented cells adjacent to peripheral retina, 4) NG2 + glial progenitors 23 Mar 2020 Schepens Eye Research Institute of Massachusetts Eye and Ear, Müller cells ( MCs) are the major type of glial cells in the retina [1]. 12 Nov 2018 Müller glia cells (MGC), the main type of glia found in the vertebrate a consistent increase in the expression of putative retinal ganglion cell  3 Dec 2019 Retinal glial cells consist of astrocytes, Müller cells and microglia.

These cells were localized in the pigmented ciliary margin and were able to clonally proliferate in vitro to form spherical colonies that differentiated into retinal-specific cell types, including rod photoreceptors, bipolar neurons, and Muller glia. Similar cells were later identified in other mammalian species, including pigs and humans, but proliferated to a lesser extent than fetal or ESC-derived retinal stem cells [66,67]. Retinal stem cells were also discovered within the iris

Müller cells are considered the main regulators of neuronal signalling within the retina, a function that they accomplish through the recycling of neurotransmitters. The main excitatory Müller cells in fish have the ability to revert back to a stem cell form and regenerate damaged eye tissue.

Müller cells constitute the dominant glial cell type in the retina. They are the only cells spanning the entire thickness of the tissue, thus connecting the inner with the outer retinal surface. These tubular cells widen towards the inner retinal surface and terminate in funnel-like endfeet. Mice without mash-1 do not exhibit any obvious abnormalities in eye development during embryogenesis and at birth, the time when the mutant mice die, 16, 17 but explant cultures of mash-1 −/− retinas showed a delay in differentiation of rod photoreceptors, horizontal cells, and bipolar cells; a decrease in bipolar cell number, and an increase in glia.

Expression of ciliary neurotrophic factor activated by retinal Müller cells in eyes with NMDA- and kainic acid-induced neuronal death. Honjo M (1), Tanihara H, Kido N, Inatani M, Okazaki K, Honda Y.

Muller cells provide homeostatic and metabolic support for retinal neurons, like the ganglions and starburst amacrines we map in Eyewire. They are retinal glial cells that wrap around the cells that form capillaries, endothelial cells and pericytes, and constitute the majority of the non-neuronal volume of the retina. The Henle fibre’s portion of parafoveal Müller cells have been measured by Drasdo et al, who reported a maximum length projected onto the ELM of 536–675 µm (nasal to the fovea) and 406–664 µm (temporal to the fovea) in six normal maculas of young adults.25 Previous studies reported shorter maximum lengths in monkey26 and in non-foveal sections of human eye.27 In the present work, R2 maximum length was shorter, as it reached a peak of 471 µm in myopic foveoschisis and 300 µm in These cells were localized in the pigmented ciliary margin and were able to clonally proliferate in vitro to form spherical colonies that differentiated into retinal-specific cell types, including rod photoreceptors, bipolar neurons, and Muller glia.

In Müller Cells in the Healthy and Diseased Retina, aimed not just at neurobiologists but at anyone concerned with retinal degeneration, every angle of Müller cells is covered, from an introduction to their basic properties, through their roles as ‘light cables’ and ‘shock absorbers’, to the part they play in diseases and disorders of the eye.
