Abstract
A composition and method for controlled release of water-soluble proteins comprising a surface-eroding polymer matrix and water-soluble bioactive factors is described. The composition bioerodes in the biological environment of the subject at a controlled rate, thereby releasing the water soluble proteins at a rate which allows them to interact with local cell populations.
