Müller cells and microglial injury responses in the retina have been ascribed both beneficial and deleterious features [ 8 – 10 ], and the "Janus-faced" nature of these responses may be secondary to the complex system of communications between microglia and macroglia.

Müller cells express numerous voltage-gated channels and neurotransmitter receptors, which recognize a variety of neuronal signals and trigger cell depolarization and intracellular Ca2+ waves. 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. Humans and mice also have Müller cells, but internal signals prevent the cell type from carrying out regenerative duties.

Within the eye, a type of cell called the Müller cell, which is found in the retina, is known to act as a stem cell in some species, such as the zebra fish. It has been suggested that this cell may also be able to act as a stem cell in humans, in which case it may provide another source of retinal cells for repair of the retina.

The loss of Müller cells seems to be coincident with the loss of macular pigment, which is Se hela listan på hindawi.com To elucidate the role of retinal Muller cells in N-methyl-D-aspartate (NMDA)- or kainic acid (KA)induced retinal damage. In experimental eyes, NMDA or KA was injected into the vitreous of rat eyes.

2015-10-01 2007-05-15 2020-02-19 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. 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. Cell line validation performed - See: Pfeffer BA, et al.

The eyes were then incubated in digestion buffer (low-glucose DMEM with 1% of antibiotic, 0.01% of trypsin, and 70 U/ml of collagenase) for 40 min at 37 °C; the retinas were removed from the eyes, transferred into culture medium (low-glucose DMEM with 10% fetal bovine serum, FBS [Sigma F2442-500 ml]), and dissociated with repeated pipetting using 1 ml. Müller cells from both species were 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 cells of stretch-activated ion channels that are permeable to monovalent and divalent cations. MATERIALS AND METHODS Cultures of retinal glial cells were prepared as de- scribed previously (Puro et al., 1990; Puro and Mano, 1991).

Dartt b, Vickery Trinkaus-Randall c, d, Jesus Pintor e, Cone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes including the human eye.They respond differently to light of different wavelengths, and are thus responsible for color vision, and function best in relatively bright light, as opposed to rod cells, which work better in dim light.Cone cells are densely packed in the fovea centralis, a 0.3 mm diameter rod-free area In all the injected eyes, we scored GFP + cells scattered through the recipient retinas. In many cases, we found cells integrated into the appropriate layer (ONL, Abbreviations: hMGC, human Muller glia cell; hMC, human Muller glia Culture; hRET, human retina.

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.

Müller cells are also responsible for the maintenance of the homeostasis of the retinal extracellular milieu (ions, water, neurotransmitter molecules, and pH).
