Preparation of Retinal Explant Cultures

Abstract

Organotypic retinal explants are routinely used as alternatives to in vitro cell culture and to replace the use of animals in modelling retinal neurodegenerative diseases. Retinal explants fill the gap between in vivo which are expensive, time consuming, and complex due to inaccessibility of target tissues. However, organotypic retinal explants are less expensive and rapid and retinal cell types in the explant maintain their morphologic interactions with other cells in the retina. Therefore, retinal explants have high potential to be used as tools to assess the pharmacological and other therapies prior to in vivo validation, reducing the use of live animals.
