Conditions for the electroporation of mouse oocytes and preimplantation embryos have been optimised by following the incorporation of rhodamine labeled dextran. This procedure includes a step to weaken but not remove the zona pellucida that helps achieve good survival. This approach has been applied to introduce double-stranded RNA for c-mos into oocytes and green fluorescent protein (GFP) into transgenic GFP-expressing embryos at the 1- and 4-cell stages. In both cases we were able to observe sequence-specific interference with the expression of the target gene-a failure of oocytes to arrest at metaphase 11 and a loss in the green fluorescence of embryos by the morula or blastocyst stages. These effects could be observed in multiple oocytes or embryos allowed to develop together following electroporation. (C) 2002 Wiley-Liss, Inc.
