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. Muller cells from chicken retina were isolated, cultured and characterized by immunocytochemical localization of cellular retinaldehyde-binding protein.

The idea that Muller cells were so important, he said, initially drew criticism from biologists and eye specialists. "There was strong opposition at the beginning, I must admit." image copyright E 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. 2014-03-25 2011-12-07 Purines in the eye: Recent evidence for the physiological and pathological role of purines in the RPE, retinal neurons, astrocytes, Müller cells, lens, trabecular meshwork, cornea and lacrimal gland Julie Sanderson a, Darlene A. 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.

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