Abstract
An apparatus is provided to enable the direct gene transfer of genetic material into a target cell site (“microseeding”), as a means of obtaining long term expression of native or non-native polypeptides in a host. The apparatus includes a matrix of microneedles that oscillate at a predetermined frequency and receive the genetic material from a delivery system that is integrated with the apparatus.
