Abstract:
Recent studies suggest that neurotrophic factors applied directly to brain tissue may enhance regeneration in the central nervous system. Biocompatible polymeric implants providing a controlled release of nerve growth factor (NGF) for over one month were developed. The released nerve growth factor stimulated neurite sprouting in cultured PC12 cells. While a model polymer with demonstrated biocompatibility was used for the present study, the methods can be extended to other polymer systems. Controlled release implants may be useful in the treatment of Alzheimer's disease.
