Cover image: Confocal image of a rat retinal section. In vivo electroporation generates expression of reporter gene constructs in retinal tissue. The gene constructs are expressed in a cell type-specific manner. Pale blue indicates photoreceptor cells, yellow highlights bipolar cells, and red shows Mu(ller glial cells. Dark blue indicates cellular nuclei. See the article by Matsuda and Cepko on pages 16–22.
