摘要

This study investigates delivery of both angiogenic and anti-angiogenic factors from spatially restricted zones of a synthetic polymer. The contradictory action of the two agents leads to a stable level of pro-angiogenic stimulation, in spite of significant variations in the individual release rates over time. Further, this simultaneous delivery achieves temporally stable and spatially restricted angiogenic zones in vivo that result in spatially heterogeneous and functional vasculature after 4 weeks in a murine model of peripheral ischemia.
