Abstract
Abstract The present invention relates to novel recombinant autonomous parvovirus vectors, novel recombinant virus particles, and novel gene delivery vehicles that can be used to selectively target heterologous nucleic acid sequences to desired cell types and to selectively express such sequences in such desired cell types. Recombinant autonomous parvovirus gene delivery vehicles are particularly advantageous for transient gene therapy, and are especially well-suited to treat diseases in which there is rapid cell growth, such as cancer. Also included is the use of recombinant vectors of the present invention to produce RNA and protein products in cell culture.
