Abstract:
Targeted ablations of genes and analysis of animal models is the classical strategy for enrolling specific retinal gene function. However, transgenic, retina-specific or conditional knockout mouse models often display early lethality or suffer from severe malformations, preventing an analysis beyond embryonic or early postnatal stages. Primary cell culture is an alternative to investigate the effects of exogenously applied recombinant factors, overexpression of genes or siRNA-mediated gene knockdown in a controlled environment. Dissociated cell culture has the advantage that the endogenous signals reaching the target cells are reduced, thereby facilitating the identification of exogenously triggered effects after pharmacological manipulation. However, important cell-cell interactions are initially destroyed by enzymatic digestion or mechanical dissociation, even if re-aggregated retinospheroid cultures are used. By contrast, organotypic retinal wholemount cultures provide a system close to the physiological in vivo situation with neuronal interactions and connections still preserved. In this video article we provide a step by step demonstration of (1) the establishment of in vivo-like organotypic retinal wholemount cultures including dissection peculiarities of embryonic, postnatal and adult murine eyes and (2) a dissociation and cytospin procedure for analysis of neuronal apoptosis and retinal cell proliferation in organotypic wholemounts, e.g. after culture in the presence of exogenously applied recombinant factors.
Insights
Organotypic retinal wholemount cultures preserve in vivo-like neuronal interactions, overcoming limitations of traditional animal models and dissociated cell cultures for studying retinal gene function.
Area of Science:
- Neuroscience
- Ophthalmology
- Developmental Biology
Background:
- Classical gene function studies in the retina rely on animal models, which often face challenges like early lethality or malformations.
- Primary cell cultures offer controlled environments but disrupt crucial cell-cell interactions.
- Existing methods struggle to maintain the in vivo complexity of retinal tissue for functional analysis.
Purpose of the Study:
- To demonstrate a robust method for establishing organotypic retinal wholemount cultures.
- To provide a detailed protocol for analyzing neuronal apoptosis and cell proliferation within these cultures.
- To offer an alternative to animal models for investigating retinal gene function and responses to external factors.
Main Methods:
- Detailed dissection techniques for embryonic, postnatal, and adult murine eyes.
- Establishment of in vivo-like organotypic retinal wholemount cultures.
- Dissociation and cytospin procedures for cellular analysis (apoptosis, proliferation).
Main Results:
- Successful establishment of organotypic retinal wholemount cultures mimicking in vivo conditions.
- Demonstration of procedures for analyzing cellular responses like apoptosis and proliferation.
- Validation of the system for studying effects of exogenously applied factors.
Conclusions:
- Organotypic retinal wholemount cultures provide a physiologically relevant system for retinal research.
- This method overcomes limitations of animal models and dissociated cultures.
- It facilitates the study of retinal gene function and pharmacological effects in a preserved tissue context.
