title: Preparation and square wave electroporation of retinal explant cultures.
abstract: This protocol details organotypic cultures of developing mouse, monkey and human retinas, which can be maintained for up to 2 weeks. Intact retinas are placed on polycarbonate filters floating on explant culture medium and fed every day with previously prepared retinal conditioned medium. Developing mouse retinas from E12.5 to P12 have been successfully cultured using this protocol as well as retinas from the equivalent stages of human and monkey development. Although this protocol does not require any special equipment, it provides a relatively high throughput. Retinal explant cultures lend themselves to complex pharmacological and genetic manipulations that are currently not feasible in vivo. A detailed procedure for square wave electroporation of retinal explants is also included to provide a high-throughput means to alter gene expression in the developing retina. This protocol for the preparation of retinal conditioned explant medium requires 4 d. Other steps of this protocol can be completed in 2 h.
