The Drosophila retina is a crystal-like lattice composed of a small number of cell types that are generated in a stereotyped manner 1. Its amenability to sophisticated genetic analysis allows the study of complex developmental programs. This protocol describes dissections and immunohistochemistry of retinas at three discrete developmental stages, with a focus on photoreceptor differentiation.

The human retina is composed of functionally and molecularly distinct regions, including the fovea, macula, and peripheral retina. Here, we describe a method using punch biopsies and manual removal of tissue layers from a human eye to dissect and collect these distinct retinal regions for downstream proteomic analysis.

This protocol describes how to dissect premigratory cranial neural crest (NC) from Xenopus laevis neurulas. These explants can be plated on fibronectin and cultured in vitro, or grafted back into host embryos. This technique allows studying the mechanisms of NC epithelium-to-mesenchyme transition, migration, and differentiation.

A method for the incorporation of plasmid DNA into murine retinal cells for the purpose of performing either gain- or loss of function studies in vivo is presented. This method capitalizes on the transient increase in permeability of cell plasma membranes induced by the application of an external electrical field.

Here we describe a cost-effective technique for organotypic culture of adult porcine retina for seven days. Briefly, a sterile filter paper was used to lift the neural retina off from the RPE and place photoreceptor side up on an insert raised by a custom-made stand.
FAQs
The critical technical principle is selective separation: the neural retina must be removed from the retinal pigment epithelium, choroid, and sclera without disrupting its organization. A stereomicroscope provides the visual control needed for this precision. Preserving orientation helps researchers relate the isolated tissue’s architecture to retinal neurons and synaptic circuitry during later analysis.
Maintaining orientation preserves the spatial context of the isolated neural tissue, allowing subsequent sections or preparations to be interpreted with cellular organization in mind. This is important when examining retinal neurons and synaptic circuitry, because their structural relationships can provide insight into visual signaling and changes associated with retinal disease.
Separating the neural retina from the retinal pigment epithelium, choroid, and sclera concentrates the preparation on the light-sensitive neural tissue. This enables more direct examination of retinal structure and function rather than analyzing the neural retina together with surrounding layers. The resulting preparation can support cellular, molecular, and disease-related investigations.
The workflow centers on careful manipulation under a stereomicroscope. Researchers isolate the neural retina by separating it from the retinal pigment epithelium, choroid, and sclera while maintaining tissue orientation and cellular organization. After isolation, the preparation may be sectioned, cultured, or processed for molecular analysis, depending on the research question.
Once isolated, the neural retina can be sectioned to examine its organization, cultured for investigation of tissue behavior, or processed for molecular analysis. These options allow researchers to study retinal neurons, synaptic circuitry, and gene expression using a preparation focused on neural retinal tissue rather than the complete surrounding eye layers.
This preparation is useful when investigators need to examine retinal changes linked to degeneration, injury, or impaired visual signaling. By providing access to neural retinal tissue, it supports studies connecting cellular structure, synaptic circuitry, and gene expression with disease-related changes. These findings can strengthen understanding of mechanisms affecting retinal function.
