17 Retinal explant cultures were also But Dr. Reh has shown that Muller glia can be reprogrammed in a dish to become neurons — cells that are closely related to photoreceptors. 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. 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. 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. By mediating transcellular ion, water, and bicarbonate transport, Müller cells control the composition of the extracellular space fluid. However, this loss of Müller cells has been observed in every eye that has been donated to the MacTel Project. While this is a small number, it provides strong evidence that Müller glia loss is part of the disease. 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.

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.

The cells are individual white blood cells floating in the aqueous. Microglia and Müller cells are cell types that feature prominently in responses to disease and injury in the retina. However, their mutual interactions have not been investigated in detail. Here, we review evidence that indicate that these two cell populations exchange functionally significant signals under uninjured conditions and during retinal inflammation.

Müller cells in the parafoveal region, unlike the central inverted plug, display a remarkable ‘z-shaped’ anatomical configuration, which has long being known since Ramon y Cajal. 6 The horizontal part of the z-shaped Müller cells contributes to the Henle's fibre layer (HFL) comprised of bundles of cone and rod photoreceptor axons terminating in the pedicles and spherules, respectively, that form synapses in the retinal outer plexiform layer (OPL).
