Delivery systems for angiogenesis stimulators and inhibitors

The development of biocompatible, controlled release systems for macromolecules has provided the opportunity to deliver angiogenesis stimulators and inhibitors. These systems have also facilitated the purification and characterization of a number of these substances. In this paper, we discuss controlled release delivery systems which release angiogenesis factors through either porous polymer matrices, degradable polymeric delivery systems or modulated polymer release systems.
