title: Novel systems for controlled delivery of macromolecules.
abstract: Gene therapy promises new treatments for human disease by alterations in the DNA content of tissues. Methods for efficient and stable introduction of genes into target cells in the body are critically important in this effort. Researchers and physicians now have many years of experience with synthetic polymers for controlled drug delivery; many of these polymers can also be used to deliver macromolecules at controlled rates to tissues. This article reviews the use of polymers in controlled protein delivery and suggests ways that polymer delivery systems may be useful in the delivery of gene transfer agents.
