In the retina of most vertebrates and even of many mammals, Müller cells are the only type of (macro-) glial cells; thus, they are responsible for a wealth of neuron-supportive functions that, in the brain, rely upon a division of labour among astrocytes, oligodendrocytes, and ependymal cells.

2006-07-01 2011-10-08 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 refractory index of Müller cells is slightly lower than that of photoreceptor segments (which are also light-guiding fibers) but higher than that of the surrounding retinal tissue. 3 On the other hand, the refractory index of Müller cell endfeet is rather low, about halfway between that of Müller cell stem processes and that of the vitreous. 3 This allows a “soft coupling” of the Müller glia cells (MGC), the main type of glia found in the vertebrate retina, can resume proliferation in the rodent adult injured retina but contribute weakly to tissue repair when compared to zebrafish retina. 2015-10-01 2007-05-15 Glial cells of the Retina by Helga Kolb 1.

Müller cells may play a role in water transport in the inner retina. RPE is estimated to transport fluid at a rate of 0.1 ?1 h?1 sqmm?1. The ion channels

Muller cells. Muller cells are the principal glial cell of the retina. They form architectural support structures stretching radially across the thickness of the retina and are the limits of the retina at the outer and inner limiting membrane respectively. Müller glia originate from neuroepithelium and are the principal glial cells in the retina. During retinal development, Müller glia are one of the last cell types to be born. In lower vertebrates, such as zebrafish, Müller glia possess a remarkable capacity for retinal regeneration following various forms of injury through a reprogramming process in which endogenous Müller glia proliferate Muller cells are the radial glial cells of the retina (Fig. 11).

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.

11 Jun 2015 In this video, I cover the retina. I discuss the five major types of neurons found in the retina: photoreceptor cells (i.e. rods and cones), bipolar

B,C: Immunofluorescence analysis of glutamine synthetase (GS, red), a M€uller glial cell marker, on transversal sections of stage 45 Xenopus laevis tadpole (B) and postnatal day 10 mouse (C) retina. Müller cells on retinal ganglion cell survival in the presence of a high level of glutamate does not depend on cell contact. In contrast, other reports have suggested that this neuroprotective effect needs cell-cell contact (Heidinger et al., 1999). The protective effect of Müller cells also seems to depend on confluence of glial cells, Muller glial cells are a retina-specific glial cell type.

Parafoveal z-shaped Müller cells were modelled as a structure composed of three rigid rods, named R1, R2 and R3. The angle formed between the rods was referred to as θ. R1, R2 and R3 lengths as well as the variation of the angle θ were measured and correlated with best corrected visual acuity (BCVA).

Figure 1 shows the arrangement of mature retinal cells in the outer, inner and ganglion cell layers. However, some of the cells are also arranged in a columnar fashion. The later-born 2018-01-29 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.
