In brief, postmortem eyes from donors aged 62 to 81 years were supplied within 24 h of death by the Specialised cells in the eye serve specific functions to focus light and turn what is being seen into signals sent to the brain. The eye contains several types of stem cells that constantly replace specialised cell that become worn out or damaged. Holoclar® is currently the only clinically approved stem cell treatment for the eye. Unlike mammals, zebrafish regenerate following retina damage from a resident adult stem cell (Müller glia). Dissecting the mechanisms that zebrafish use could lead to new therapeutic targets to treat retinal diseases.

Patton and colleagues have discovered a mechanism by which decreased GABA levels are sensed by Müller glia to initiate a regenerative response. 2Inci Eye Hospital, Sakarya, Turkey Abstract A coincidence of Muller cell sheen dystrophy (MCSD) and congenital color vision deficiency in a 36 years old man is presented in this case report. Best corrected visual acuity (BCVA) was 1.0 in both eyes. He failed to read Ishihara color plates (0/13 in both eyes). 2007-03-01 (1993). Muller cell expression of glial fibrillary acidic protein (GFAP) in WE-cell transplanted retinas of RCS dystrophic rats.

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. Their functions include providing anatomical, metabolic and functional support 8 Jul 2014 It has been recently reported that retinal Müller cells act as light guides serving to transfer light across the retina, from the vitreo-retinal border Bignami, A. and Dahl, D. (1979) The radial glia of Müller in the rat retina and their (1986) Endfeet of retinal glial cells have higher densities of ion channels that These Müller glial cell-derived iPSCs were able to differentiate toward retinal fate and generate concomitantly retinal pigmented epithelial cells and self-forming 12 Sep 2018 Bipolar cells along with amacrine cells help transmit the photoreceptor signal to retinal ganglion cells (RGCs), whose axons exit the retina The Müller cell cone serves as a plug to bind together the receptor cells in the foveola. Without this plug of glial cells, the retinal receptor cell layer with its thin These retinal layers contain numerous objects which differ in shape and refractive index, which should lead to scattering, refraction and reflection of the light on its Müller glia, or Müller cells, are a type of retinal glial cells, first recognized and described by Heinrich Müller.

To dissect the role of vascular endothelial growth factor receptor-2 (VEGFR2) in Müller cells and its effect on neuroprotection in diabetic retinopathy (DR), we disrupted VEGFR2 in mouse Müller glia and determined its effect on Müller cell survival, neuronal integrity, and trophic factor production in diabetic retinas. Diabetes was induced with streptozotocin. Retinal function was measured Müller cells are the predominant glial cell type in the retina of vertebrates. They play a wide variety of roles in both the developing and the mature retina that have been widely reported in the literature. Müller cells, the major type of glial cells in the retina, are responsible for the homeostatic and metabolic support of retinal neurons.

These cells, Müller cells, are radial glial cells in the inner vertebrate retina, which have a cylindrical, fiber-like shape (their original name was “radial fibers of Müller”) ( 10 ).

Much more work remains, but if he can derive photoreceptors from Muller glia in a mammal such as a mouse, it would be a major step toward making retinal regeneration possible in humans.

Müller cells are also responsible for the maintenance of the homeostasis of the retinal extracellular milieu (ions, water, neurotransmitter molecules, and pH). In vascularized retinae, Müller cells may also be involved in the control of angiogenesis, and the regulation of retinal blood flow.
