Large-Scale Purification of Porcine or Bovine Photoreceptor Outer Segments for Phagocytosis Assays on Retinal Pigment Epithelial Cells

This article describes the protocol for the purification of photoreceptor outer segment fragments (POS) via ultracentrifugation from porcine/bovine retinae using homogenization and sucrose gradient centrifugation. This protocol allows the preparation of large stocks of POS aliquots, labeled or unlabeled, that can then be stored at -80...

Müller Glia Cell Activation in a Laser-induced Retinal Degeneration and Regeneration Model in Zebrafish

The zebrafish is a popular animal model to study mechanisms of retinal degeneration/regeneration in vertebrates. This protocol describes a method to induce localized injury disrupting the outer retina with minimal damage to the inner retina. Subsequently, we monitor in vivo the retinal morphology and the Müller glia response throughout retinal...

Modeling Retinal Degeneration and Regeneration in Zebrafish Using a Focal Laser Injury

Modeling Retinal Degeneration and Regeneration in Zebrafish Using a Focal Laser Injury

This video demonstrates a procedure to induce retinal degeneration in adult zebrafish using laser injury. The laser targets photoreceptor cells in the retina, triggering cell death and a degenerative process. This damage activates Müller glia (MG) cells, leading to their dedifferentiation into stem cell progenitors that aid in retinal...

Two-Photon Microscopy for Monitoring Calcium Dynamics in Mouse Retinal Cone Photoreceptors

Source: Kulkarni, M. et al. Imaging Ca2+ Dynamics in Cone Photoreceptor Axon Terminals of the Mouse Retina. J. Vis. Exp. (2015)This video demonstrates the use of two-photon microscopy to monitor calcium dynamics in cone photoreceptors of a transgenic mouse retina. It outlines the steps for preparing retinal slices, imaging FRET-based calcium biosensors, and analyzing fluorescence changes to quantify calcium levels under background illumination and light...

Simultaneous Whole-cell Recordings from Photoreceptors and Second-order Neurons in an Amphibian Retinal Slice Preparation

We describe the preparation of thin retinal slices from aquatic tiger salamanders (Ambystoma tigrinum) and explain how we use these slices to study synaptic processing in the retina by obtaining dual whole-cell voltage clamp recordings from photoreceptors and second-order horizontal and bipolar...
