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.

Establishing a Müller Glial Cell Culture Obtained from Mouse Retinas

This video demonstrates the culturing of Müller glial (MG) cells isolated from mouse retinas. Retinas are dissociated into a single-cell suspension using digestive enzymes. Cells are then grown in a medium with a growth factor that promotes MG cell proliferation and neuronal cell mortality. Dead neuronal cells are removed while passaging, and MG cells are grown for further analysis.

The overall goal of this video is to show how to perform targeted retinal injection and in ovo electroporation of DNA/RNA constructs into the chick embryonic retina at the Hamburger and Hamilton stage 22-23, which is about embryonic day 4 (E4). This technique is very useful to study gene expression, gene regulation, and morphological change in developing chick retina.
FAQs
Retinal explants retain tissue-level organization, while dissociated cultures separate retinal cells for more cell-focused investigations. Explants are therefore suited to examining structure, synaptic organization, and coordinated neuronal signaling. Isolated cells can emphasize differentiation and cellular responses to experimental conditions. Selecting one format over the other determines which level of retinal biology remains accessible during the study.
Nutrient media, temperature, gas exchange, and osmolarity are central variables because they determine whether retinal tissue or cells remain viable and continue developing. These conditions must be regulated rather than treated as incidental features of the experiment. Appropriate control supports meaningful investigation of retinal structure, function, differentiation, and responses to injury or disease.
Tissue organization provides a context for examining how retinal neurons are arranged and how synapses are organized within the tissue. This is especially relevant when the goal involves neuronal signaling or synaptic relationships rather than isolated cellular behavior. Maintaining that organization can help researchers connect cellular observations with broader structural and functional features of the retina.
A basic workflow begins by selecting either a retinal explant or dissociated retinal cells according to the experimental question. The preparation is then maintained in nutrient media under controlled temperature, gas exchange, and osmolarity. Researchers can subsequently examine survival, development, differentiation, signaling, synaptic organization, or responses to injury and disease within the selected culture format.
Retinal cultures provide controlled platforms for observing how retinal tissue or cells respond to injury- or disease-related experimental conditions. Depending on the preparation, investigators can examine effects on cellular survival, development, neuronal signaling, synaptic organization, or differentiation. This controlled setting helps separate retinal responses from the complexity of studying these processes only in an intact organism.
These cultures serve as experimental platforms for testing drugs and investigating neurodegeneration. They also support evaluation of strategies aimed at retinal repair and regeneration by providing retinal tissue or cells in conditions where responses can be examined. In neuroscience, this links cellular and tissue-level observations with efforts to understand disease processes and develop restorative approaches.
